Morphological, Ultrastructural, and Immunocytochemical Characterization and Assessment of Puma ( Linnaeus, 1771) Cell Lines After Extended Culture and Cryopreservation.

Cell lines are valuable tools to safeguard genetic material from species threatened with extinction that is mainly due to human action. In this scenario, the puma constitutes a species whose population is being rapidly reduced in the ecosystems it inhabits. For the first time, we characterized puma skin-derived cell lines and assessed these cells after extended culture (experiment 1) and cryopreservation (experiment 2).
