Functional and molecular changes in colony stimulating factor secretion by osteoblasts.

abstract：:The molecular substructure of human articular cartilage has been difficult to study because of its complex composition and high degree of hydration. Using newly available small-angle X-ray diffraction (SAX) instrumentation that allows very short exposure times (0.1 to 10 sec), we have obtained spatially resolved infor...
