Interaction of Hormones with Receptors and Alterations of These Processes with Age cases, however, there is no change; and in a few situations there may actually be increases in sensitivity. However, the large majority of changes for many different hormones, target cells, and tissues are post-maturational reductions in responsivenss.

Change of Responsiveness to Growth Stimulation of Normal Cells during Agingstigations, however, suggest that extracellular factors can affect the proliferative potential of the cells. For example, hydrocortisone (4) and epidermal growth factor (5) elongate the life span of fibroblasts and keratinocytes, respectively. .. experiments also suggest that the milieu in old anima

Mechanism of Age-Dependent Decrease in Sulfation of Chondroitin Sulfatethe amount of hexosamine-containing substances in tissue decreases with age, while the insoluble collagen content in the tissue increases with age (3). Recently, it has been reported that the decrease in elasticity of cartilage with age is related to the content and structure of the proteoglycan in

The Aging Process in the Neurons received a greater amount of attention as a model for the study of aging processes than any other cell type. Additional interest in the neuron as a subject for aging studies stems from the view that that these elements, in strategic locations in the nervous system, may function as pacemakers, or t
