Figure 1: Adipose derived stem cells (ASCs) in culture at passage 3. They were presented with the spindle shape appearance before differentiation (a) and appeared with rounder and cuboidal shapes after chondrogenic differentiation (b) [23]. The flow cytometric analysis of ASCs showed that more than 98% of all cells were positive for the expression of CD44, CD105 and CD166. Absence of CD14, CD34 and CD45 expressions on the surface of ASCs were observed. Filled histograms represent the specific markers (CDs) and unfilled were isotype control (Figureure 1c) [22].
