The parameters of stimulation of neonatal B cells were similar to those of adult B cells but the antibody-forming cell progeny of neonatal B cells produce predominantly .M rather than .G antibo

Two hypothetical examples of such mechanisms are described; however, the available evidence argues against a clock mechanism for aging in fibroblasts. .) Cells become committed

The actual limit of reproductive cell life would therefore not likely be reached in a normal life-span. It is proposed to test the hypothesis by deliberate exhaustion of stem-cell reserve, and iron-55 cy
