| Research Abstract |
Previous studies show that, in placental mammals such as rats, the mode of wound healing transits from the fetal-type to adult-type during the fetal stage. This study aimed at morphological characterization in vivo as well as in vitro of the wound repair capability of the skin of a marsupial gray short -tailed opossum (Monodelphis domestica) which is known to be born in a very "premature" state, and revealed that the mode of healing depended on the events chosen as the evaluation criteria. Further analyses on the possible marsupial uniqueness, with respect to the heterochrony that one-day neonates already have a cornified epidermis, are promising for elucidation of the establishment of tissue rapair ability in marsupials.
