A qualitative and quantitative description of the columnar units in the mammalian retina, and a discussion of their ontogeny and putative functions is given. Columnar arrangements of cells exist in the developing retina which can be observed by means of scanning electron microscopy. In the adult retina, each Müller cell ensheaths a columnar group of(More)
The balance between ER-alpha and ER-beta in fibroblasts may be crucial in the physiological response to ligands. Up- or down-regulation of the ERs in response to different compounds could mediate the reversal of certain age-related changes in skin and connective tissue. The time-dependent effects of 17-beta estradiol, raloxifene and tamoxifen on ER-alpha(More)
