✦ Synopsis

Collagen solutions (0.25% w/v) were polymer-side illumination of the gels revealed the more granular apized in microgravity (STS-77, 10 days) along with simultane-pearance of the ground gels relative to the highly uniform ous ground controls. Assembly conditions were achieved by appearance of the flight gels. Scanning electron microscopy the passage of buffer ions across a dialysis membrane into established this difference at the microscopic level. Proximity a reaction chamber containing the dissolved collagen. The to the dialysis interface and the presence or absence of gravity gels were analyzed macroscopically and microscopically to were both found to control the porosity and uniformity of assess the influence of gravity and the oriented diffusion of the matrix.
