Mesenchymal Stem Cells (MSCs) are adult stem cells which can be isolated from human source. Human MSCs (hMSCs) are the non-haematopoietic, multipotent stem cells with the capacity to differentiate into mesodermal, endodermal and ectodermal lineages. MSCs express cell surface markers like cluster of differentiation (CD) 29, CD44, CD73, CD90, CD105 and lack the expression of CD14, CD34, CD45 and HLA (human leucocyte antigen)-DR. For the first time, hMSCs, were described in the bone marrow and till now they have been isolated from various sources, as adipose tissue, amniotic fluid, endometrium, dental tissues, and umbilical cord. hMSCs are able to maintain their stemness properties and features for long-term in vitro passage. MSCs show immunomodulatory features, release cytokines and immune-receptors which regulate the microenvironment in the host tissue.
Manipulation of stem cells or stem cells-derived secretome has emerged as a novel alternative therapeutic option for several diseases or in regenerative medicine in order to improve scaffold effects. Stem cells secretome exert its therapeutic effects mainly through the paracrine signaling of exosomes/microvesicles secreted into cell culture conditioned medium. These are small membrane vesicles released by a variety of cell types, containing functional cytokines and other proteins, lipids and nucleic acids, such as mRNA and microRNA. The soluble bioactive molecules present in the conditioned medium directly activate the target cells, suppress pro-inflammatory responses, modulate the immune system, inhibit apoptosis and fibrosis, and stimulate tissue-intrinsic progenitor cells differentiation. The stem cells secretome could provide a novel cell-free regenerative therapeutical approach in various diseases and in regenerative medicine.
Then, to evaluate the aptitude of secretome derived from stem cells in terms of tissue regeneration we invite authors to contribute with original research articles, reviews and opinion letters focused on the use of secretome-derived stem cells for future clinical applications.
Potential topics include but are not limited to the following:
•Mesenchymal stem cells models for drug personalized therapy;
•Functionalized biomaterial with mesenchymal stem cells;
•Functionalized biomaterial with secretome;
•Mesenchymal stem cells secretome;
•Mesenchymal stem cells models of systemic and genetic diseases.

- Inflammatory priming of mesenchymal stem cells: Focus on growth factors enhancement
- BIOCELL, DOI:10.32604/biocell.2022.019993
- (This article belongs to this Special Issue: Mesenchymal Stem Cells, Secretome and Biomaterials: Regenerative Medicine Application)
- Abstract Multipotent mesenchymal stromal cells (MSCs) are actively involved in reparation and inflammation processes, providing damaged tissue reparation and suppressing immune cell responses in vivo. The effects are mostly due to the production of a wide range of paracrine factors, including growth factors and immunomodulatory mediators. To induce immunosuppressive activity, MSCs are primed by inflammatory cytokines, which results in an increased production of immunomodulatory molecules. However, stimulation of reparative properties is also necessary. This viewpoint manuscript highlights the possibilities of inflammatory priming to increase the production of growth factors by MSCs.

- Abstract Mesenchymal stem cells (MSC) have pushed the field of stem cell-based therapies by inducing tissue regeneration, immunosuppression, and angiogenesis mainly through vesicles and soluble factors release (paracrine signaling). MSC-extracellular vesicles (MSC-EV) adaptable secretome and homing to injured sites allowed researchers to unlock a new era of cell-free based therapy. In parallel, nanoparticles (NP) have been explored in contributing to transport and drug delivery systems, giving drugs desired physical-chemical properties to exploit cell behavior. However, NPs can be quickly recognized by immune cells and cleared from circulation. In this viewpoint, we explore how combining both therapeutic strategies can improve efficacy and… More

This adult stem cell type exhibit unique features of tissue repair mechanism and immune modulation mediated by their secreted factors, called secretome. Recently, the utilization of secretome as a therapeutic agent provided new insight into cell-free therapy. Nevertheless, a sufficient amount of secretome is necessary to realize their applications for translational medicine which required a proper biomanufacturing process. Several factors related to their production need to be considered to produce a… More

- Abstract The treatment of nonhealing and chronic cutaneous wounds still needs a clinical advancement to be effective. Both mesenchymal stem cells (MSCs), obtained from different sources, and their secretome derived thereof (especially exosomes) can activate signaling pathways related to promotion of cell migration, vascularization, collagen deposition, and inflammatory response demonstrating prohealing, angiogenetic and anti-scarring capacities. On the other hand, biodegradable biomimetic scaffolds can facilitate endogenous cell attachment and proliferation as well as extracellular matrix production. In this Review, we revise the complex composites made by biomimetic scaffolds, mainly hydrogels, and MSC-derived exosomes constructed for cutaneous wound healing. Studies demonstrate that there… More

- Abstract Human adipose stem cells (hADSCs) are reliable sources for cell therapy. However, the clinical applications are limited by the decrease in activity during in vitro culture. We used a knockout serum replacement (KSR) medium, Eppendorf (EP) tube culture, and a simulated microgravity (SMG) culture system to establish hADSC spheroids. We found that hADSCs aggregated and formed spheroids in the KSR culture medium. The EP tube culture method revealed many biological cell characteristics, such as good cell viabilities, rough surfaces, polar growth, fusion phenomenon, and injectability. The findings show its advantages for hADSCs spherical cultures. When cultured in SMG, hADSC spheroids… More

- Precise tissue bioengineering and niches of mesenchymal stem cells: Their size and hierarchy matter
- BIOCELL, Vol.46, No.6, pp. 1365-1373, 2022, DOI:10.32604/biocell.2022.018917
- (This article belongs to this Special Issue: Mesenchymal Stem Cells, Secretome and Biomaterials: Regenerative Medicine Application)
- Abstract Stem cell microterritories (niches), as a specialized part of the extracellular matrix (ECM), are considered an important target and tool for the development of new materials, medical implants, and devices. However, tissue bioengineering products that have stem cell niches of known size on the surface or in the bulk structure of artificial materials are practically unknown. This brief review attempts to draw attention to the problematic aspects of niches as specific parts of the ECM, such as their hierarchy and size for mesenchymal stromal/stem cells (MSCs). These parameters arise directly from numerous definitions of stem cell niches as specialized morphological… More

- Abstract Mesenchymal stem cells (MSCs) and their byproducts have been widely validated as potential therapeutic products for regenerative medicine. The therapeutic effects result mainly from the paracrine activity of MSCs, which consists of the secretion of bioactive molecules, whether dispersed in medium conditioned by cell culture or encapsulated in extracellular vesicles. The composition of the MSC secretome, which represents the set of these secreted cellular products, is crucial for the performance of the desired therapeutic functions. Different cell culture strategies have been employed to adjust the secretome composition of MSCs to obtain the best therapeutic responses for different clinical contexts. However,… More

- (This article belongs to this Special Issue: Mesenchymal Stem Cells, Secretome and Biomaterials: Regenerative Medicine Application)
- Abstract Exogenously delivered mesenchymal stromal cells (MSCs) are therapeutically beneficial owing to their paracrine effect; they secrete various cytokines, nucleic acids, and proteins. Multiple bioengineering techniques can help MSC cultures to release secretomes by providing stem cell niche-like conditions (both structurally and functionally). Various scaffolds mimic the natural extracellular matrix (ECM) using both natural and synthetic polymers, providing favorable environments for MSC proliferation and differentiation. Depending on material properties, either topographically or elastically structured scaffolds can be fabricated. Three-dimensional scaffolds have tunable substrate rigidities and structures, aiding MSC cultivation. Decellularized ECM-derived hydrogels are similar to the natural ECM, thus improving the… More

- (This article belongs to this Special Issue: Mesenchymal Stem Cells, Secretome and Biomaterials: Regenerative Medicine Application)
- Abstract Stemness of cancer cells contains limitless self-renewal proliferation. For the purpose of proliferation, secretome might exert its effects via the paracrine signaling. Specific microRNAs enclosed in the secretome of cancer stem cells could regulate the expression of anti-proliferative APRO family proteins. The biological functions of APRO family proteins seems to be quite intricate, however, which might be a key modulator of microRNAs, then could regulate the proliferation of cancer cells. In addition to affecting proliferation/differentiation during cellular development, APRO family proteins might also play an imperious role on keeping homeostasis in healthy stem cells under a physiological condition. Therefore, relationship… More

- Mesenchymal stem cells-derived extracellular vesicles as ‘natural’ drug delivery system for tissue regeneration
- BIOCELL, Vol.46, No.4, pp. 899-902, 2022, DOI:10.32604/biocell.2022.018594
- (This article belongs to this Special Issue: Mesenchymal Stem Cells, Secretome and Biomaterials: Regenerative Medicine Application)
- Abstract Mesenchymal stem cells (MSCs) have abilities to mediate tissue protection through mechanisms of anti-apoptosis, anti-oxidative stress and anti-fibrosis as well as tissue regeneration through mechanisms of cell proliferation, differentiation and angiogenesis. These effects by MSCs are mediated by a variety of factors, including growth factors, cytokines and extracellular vesicles (EVs). Among these factors, EVs, containing proteins, mRNA and microRNAs (miRNA), may carry their contents into distant tissues with high stability. Therefore, the treatment with MSC-derived EVs may be promising as ‘natural’ drug delivery systems (DDS). Especially, the treatment of MSC-derived EVs with the manipulation of specific miRNAs expression has been… More

- Abstract Though mesenchymal stem cells (MSCs) are considered as an important pillar of regenerative medicine, their regenerative potential has been shown to be limited in several pathological conditions. The adverse properties of MSC-based cell therapy have drawn attention to the therapeutic use of MSC-derived secretome. However, MSC-originated exosomes and microvesicles can also possess a significant impact on disease development, including cancer. By interchanging secretome, MSCs can interact with tumor cells and promote mutual exchange/induction of cellular markers. In addition, enzymes secreted into and activated within exosomes can result in the acquisition of new tumor cell properties. Therefore, therapeutic applications of MSC-derived… More
