Figure 3. Contraction of 3D collagen gels.

Figure 3

HeLa, LNCaP, MCF7, MCF10A, HUF and primary prostate cells were seeded in 24 well dishes in liquid collagen. After the collagen hardened, the gels were released from the sides of the wells and allowed to contract for 24 hrs. The wells were photographed from above at the times shown. Note that the HUF and primary prostate cells contract the gels to a greater extent than HeLa and LNCaP cells and that MCF 10A cells contract more than MCF-7 cells. Scale bar = 2 mm.
