This hypothesis is supported by the ndings of Hassell et al. 53 who located that covering cultures having a layer of agarose leads to improved deposition of matrix and cell stratication. There are numerous choices of how TGF one can cause elevated matrix dep osition and cell stratication. The rst would just be that TGF one stimulates more matrix part synthesis top to far more matrix and more cell stratication. A second likelihood is TGF one stabilizes the collagen brils created, thus top to increased stratication. Lastly, its probable the altered matrix composition in TGF one treated cells prospects to increased stratication. This possibility is supported by the TEM and immunouorescence data in Figures two and 4, the place the best portions from the constructs expressing highest levels of sort III collagen and EDA Fn were the same locations that in TEM appeared to possess the longest brils and highest density of matrix.

As a result, knowing the mechanisms that underlie MDSC differenti ation and developing new tactics to create huge numbers of MDSC in vitro are of clinical relevance.
