    TLDR Human scalp fat stem cells showed improved cartilage-like development on a special scaffold with freeze-thaw treatment.
    The 2018 study investigated the potential of human scalp adipose-derived stem cells (SADSCs) for chondrogenic differentiation using a Polycaprolactone (PCL) scaffold combined with a Freeze Thaw Freeze (FTF) method. The SADSCs were characterized and found to express specific surface markers (CD90, CD44, and CD105) and not CD45. When induced with growth factors TGF-beta3 and BMP-6, the cells showed increased expression of chondrogenic markers (collagen type II, aggrecan, and SOX9) and enhanced differentiation and proliferation on PCL scaffolds with FTF treatment compared to PCL alone. These findings suggest that the PCL+FTF scaffold could be a promising approach for cartilage tissue engineering. The study included various methods such as flow cytometry, histology, immunohistology, and real-time PCR, and the results were statistically significant. However, the number of people from whom the SADSCs were isolated was not mentioned.
