Acetylcholine receptors (AChR) are organized in a discrete and predictable fashion in the postsynaptic regions of vertebrate skeletal muscle. When muscle is damaged, nerves and myofibers including muscular elements of the endplate degenerate, but the connective tissue elements survive. Muscle fibers regenerate within the basal lamina of the original myofiber. Postsynaptic differentiation in regenerated mammalian skeletal muscle can occur in different ways: (a) at the site of the original endplate in the presence or absence of the nerve, or (b) at ectopic regions of the regenerated myofiber in the presence of the nerve when the original endplate is not present. The present study used (125)I-α- bungarotoxin ((125)I-α-BuTX) and EM autoradiography to examine the density and distribution of AChR in postsynaptic structures regenerated at the site of the original endplate in the absence of the nerve and at ectopic sites of the myofiber in the presence of the nerve when the original endplate was removed. In regenerated myofibers, the density of α-BuTX-binding sites fell within the range of densities observed in uninjured muscle whether postsynaptic differentiation occurred at the site of the original endplate in the absence of the nerve or at an originally ectopic position of the regenerated myofiber. In addition, the distribution of α-BuTX-binding sites within the regenerated postsynaptic regions closely resembled the distribution of apha-BuTX- binding sites in uninjured muscle. Morphometric analysis was performed on postsynaptic structures formed at the site of the original endplate in the absence of the nerve or at an ectopic position of the regenerated myofiber by interaction of the nerve and muscle. Although variation in the depth of the primary cleft occurred, there was little difference between the overall structure of regenerated postsynaptic structures and that of endplates of uninjured muscles.

After injection of [3H]-1,25(OH)2-vitamin D3 (soltriol), nuclear labeling is found in Sertoli cells of testes, being highest at the stage of spermiosis, in epithelium of efferent ductules and caput epididymidis and in connective tissue cells of epididymis, in lamina propria and muscular sheath of deferent duct, and in epithelium and muscular sheath of dorsal and ventral prostate of the mouse. This labeling pattern is characteristic for [3H]-soltriol and differs from that for [3H]-dihydrotestosterone and [3H]-estradiol, although with overlap. The nuclear labeling with [3H]-soltriol suggests an action of the hormone on certain processes during spermatogenesis, on sperm maturation, on epididymal fluid resorption, and on secretion and transport of spermatozoa.
