Podosomes are actin rich structures found in cancer cells and cells derived from monocytes in the human body. They help these cells be motile through the body and invade through tissues. We found the number of podosomes observed in the cells increased, with a simultaneous increase in motility, corresponding to an increase in the concentration of Epigallocatechin gallate(EGCG) used in a dose-dependent fashion. We also found that the actin molecules in the podosomes are arranged in columns with frequent breaks in its structure. We also found myosin llb to be an integral part of the podosome, providing the podosome with the banding pattern along with actin. We were also able to confirm the presence of gelsolin in the podosome and assembled together a model trying to explain the interaction among all these proteins.
