The vitamin D-induced calcium-binding protein (CaBP) was localized in histological sections of chick duodenum using the peroxidase-antiperoxidase immunocytochemical technique. The time-course of appearance of CaBP in rachitic chicks was investigated from 0 to 120 hr after stimulation by 1,25-dihydroxyvitamin D3 (1,25(OH)2D3). CaBP was not routinely detected at 0 hr after 1,25(OH)2D3 administration. CaBP was first noted in some, but not all, of the samples taken 2 hr following 1,25(OH)2D3 and was detected in all 2 1/2 hr samples. The number of CaBP-containing absorptive cells and the apparent CaBP concentration both increased to a maximum at about 16-24 hr. At later times, as CaBP free cells migrated up the villi, the CaBP-containing cells decreased in number, but even at 120 hr post 1,25(OH)2D3 dose there were significant numbers of CaBP-containing cells present. The relationships between time-course of CaBP location on intestinal villi, enterocyte migration rates, and the time-course of 1,25(OH)2D3 stimulated intestinal calcium transport are discussed.
