Aim: To find a method for isolation and cultivation of human adipose-derived mesenchymal stem cells(ADSCs), and to investigate its chondrogenic ability.
Methods: Liposuction human adipose tissues were digested with collagenase type II. The obtained cells were primarily cultured in DMEM medium, and then changed into the induced medium. Alcian Blue stain, picrosirius red stain and the specific collagenase type II immunohistochemical staining were used to detect the results.
Results: After cultured in chondrogenic medium, the cells differentiated toward cartilage cells and secreted the specific cartilaginous matrices sulfated proteglycan and collagen type II.
Conclusion: The human ADSCs have the potential ability to differentiate toward cartilage cells in the appropriated medium. The result provide a new method for the further research in cartilaginous tissue engineering.

Feline Idiopathic Cystitis (FIC), is a chronic lower urinary tract condition in cats analogous to PBS/IC in women, which presents significant treatment challenges due to its idiopathic nature. Recent advancements in regenerative medicine highlight the potential of Adipose Tissue-Derived Stem Cells (ADSCs), particularly through their secretome, which includes mediators, bioactive molecules, and extracellular vesicles (EVs). Notably, exosomes, a subset of EVs, facilitate cell-to-cell communication and, when derived from ADSCs, exhibit anti-inflammatory properties and contribute to tissue regeneration.

Background: Current therapies for complex Crohn's perianal fistulas (CPF) have a limited ability to achieve long-term healing. Darvadstrocel (DVS) is an expanded allogeneic adipose-derived mesenchymal stem cell therapy that has demonstrated efficacy in treating complex CPF in clinical trials. There are, however, limited long-term comparative data with standard of care (SoC).

Pulmonary fibrosis (PF) is a medical condition that affects the lungs and causes scarring due to the deposition of excess fibrotic tissue. This is often preceded by various causes and can lead to long-term health consequences. The treatment of PF using mesenchymal stem cells (MSCs) to correct lung damage and decrease inflammation is a current focus of research.

Background: The therapeutic potential of mesenchymal stem cells (MSCs) may be partly attributed to their secretion growth factors, cytokines and chemokines. In various preclinical studies, the use of MSC-conditioned media (CM) has demonstrated promising potential for promoting vascular repair.
Methods: To gain a comprehensive understanding of the variations in conditioned media derived from different sources of mesenchymal stem cells (MSCs) including umbilical cord, adipose and bone marrow, we investigated their reparative effects on human umbilical vein endothelial cells (HUVECs) subjected to damage induced by high glucose.

Interactions between MSCs and cancer cells are complex and multifaceted and have been shown to exhibit both pro-tumor and antitumor effects. This study investigated the effects of conditioned medium (CM) and cell extract (CE) from two different ERα statuses, MCF-7 and MDA-MB-231 breast cancer cell lines, on adipose-derived mesenchymal stem cells (ASCs). Findings showed that CM and CE increased cellular metabolic activity and viability of ASCs, upregulated angiogenic factors VEGF and HIF-1α, and cytokine TGF-β expression levels.
