And Function

The size and organization of collagen fibrils in the extracellular matrix is an important determinant of tissue structure and function. The synthesis and deposition of collagen involves multiple steps which begin within the cell and continue in the extracellular space. High-voltage electron microscopic studies of the chick embryo cornea and tendon suggested that the extracellular space is compartmentalized by the fibroblasts for the regulation of collagen fibril, bundle, and tissue specific macroaggregate formation. The purpose of this study is to gather direct evidence regarding the association of the fibroblast cell surface with newly formed collagen fibrils, and to define the role of the fibroblast in the control and the precise positioning of collagen fibrils, bundles, and macroaggregates during chick tendon development.

AbstractIntrafibrillar mineralization of type-I collagen with hydroxyapatite (HA) is the basis of the complex biological composite known as bone, which from a material science perspective is a fascinating example of an interpenetrating bioceramic composite. Using a polymer-induced liquid-precursor (PILP) process, collagen substrates were highly infiltrated with a liquid-phase mineral precursor to calcium carbonate (CaCO3). At sections of partially mineralized collagen, banded mineral patterns were observed perpendicular to the collagen fibrils, while other fibrils were completely mineralized. An acid etch, used to preferentially remove superficial mineral, further revealed such banded patterns in fully mineralized samples. Removal of the collagen matrix with a dilute hypochlorite solution showed an interpenetrating mineral phase, with mineral disks that spanned the diameter of the pre-existing collagen fibrils, supporting our hypothesis that intrafibrillar mineralization can be achieved via capillary action applied to a liquid-phase mineral precursor.

Ultrastructural Studies

Ultrastructural studies from tissues of Peruvian mummies ranging from 500 to 2000 years old have been carried out.Even though the tissues had undergone extensive autolytic alterations many subcellular structures were still present and it was possible to clearly identify them. The better preserved tissues were those which contained abundant collagen and connective structures (Fig. 1-3). The collagen fibrils in particular showed the characteristic cross striations. The thickness of the dark bands was 45-50 nm while the thickness of the light bands measured between 25-30 nm.
