We investigated the capacity of a clonal osteogenic cell line MC3T3-E1, established from newborn mouse calvaria and selected on the basis of high alkaline phosphatase (ALP) activity in the confluent state, to differentiate into osteoblasts and mineralize in vitro. The cells in the growing state showed a fibroblastic morphology and grew to form multiple(More)
The ontogenetic development of cholecystokinin-immunoreactive (CCK-IR) cells was studied in larval ayu, Plecoglossus altivelis. This species has a straight digestive tract during the larval phase. CCK-IR cells were present in all the larvae from the day of hatching (0 days after hatching, DAH). An immunoreaction to anti-trypsinogen antibody was also(More)
