## Abstract Subsequent to excision and explantation of the limb blastema into culture medium, there is an abrupt reduction in mitotic index lasting several hours. Coincident with the disappearance of mitosis, abnormal mitotic figures (AMFs), lacking the condensed chromosomal nature of normal figure
## Abstract Evidence is presented that regenerating portions of newt limbs preferentially accumulate ^3^Hβlabelled exogeneous cortisol and corticosterone. The ability of such regions to accumulate glucocorticoids is maximal about seven days after amputation and is abolished by interrupting the spin
## Abstract Preparations of ungulate growth hormone that have been used thus far to establish the role of that compound in supporting limb regeneration in hypophysectomized newts have contained significant prolactin contamination. Prolactin when present with thyroxin has been shown to be effective
## Abstract Cyclophosphamide (cytoxan), a clinical immunosuppressant, produced a marked, persistent leukopenia (> 40% reduction) in adult newts in contrast to a transient, milder leukopenia accompanying amputations without cytoxan treatments. In addition, cytoxan suppressed the formation of regener
