Chondrogenic differentiation of mesenchymal stem cells derived from Wharton’s jelly of human umbilical cord on two different nanofibrous scaffolds, the PLLACL and collagen, here referred to as PC; and the PLLACL, collagen and rhTGF-β3, here named PC@rhTGF. (a) Real time-qPCR analysis of chondrogenic markers SRY-box transcription factor 9 (So × 9) and collagen type II (COL2) after culturing for 14 days (n = 3, * P < 0.05). (b) Histological staining of glycosaminoglycans synthesized by the mesenchymal stem cells derived from Wharton’s jelly of human umbilical cord with Toluidine and Safranin O after culturing for 21 days (used with permission from [178]).
