Effect of adipose-derived mesenchymal stromal cells on tendon healing in aging and estrogen deficiency: an in vitro co-culture model

Findings suggest that ADSCs might be a promising treatment for tendon regeneration in advanced age and estrogen deficiency. However, some differences between allogenic and autologous cells were found and should be investigated in further in vivo studies. It appears that allogenic ADSCs improve tenocyte proliferation, collagen expression and the healing rate more than autologous cells. Autologous cells increase collagen expression only in the absence of an injury and increase Decorin and Tenascin C more than allogenic cells.
