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)

The crude histaminase preparation obtained from guinea pig skin was fractionated by Sephadex G-200 at 4°C and 55°C. The histaminase activity corresponded to the descending limb of the :first peak of protein eluted just after void volume at 4°C and to the second peak at 55°C. The histaminase activity in the fractions eluted at 4°C was higher at 55°C than at(More)
