FACS analyses of keloid and palmar fibroblasts embedded in collagen I gels. Keloid (a-c) and palmar (a'-c') fibroblasts in gels incubated for three days either with serum (a, a') or with serum and TGFβ1 (b, b', c, c'). Attached* – gels with keloid fibroblasts (a, b) were partially detached, self shrinking and remaining attached only in the center, while the gels with the palmar fibroblasts were fully attached – (a' b'). Relaxed gels (c, c') were fully floating in the media.
