Comparative cellular biogerontology: Where do we stand?

Abstract: Due to the extreme variation in life spans among species, using a comparative approach to address fundamental questions about the aging process has much to offer. For example, maximum life span can vary by as much as several orders of magnitude among taxa. In recent years, using primary cell lines cultured from species with disparate life spans and aging rates has gained considerable momentum as a means to dissect the mechanisms underlying the variation in aging rates among animals. In this review, we reiterat… Show more

“…cellular senescence; noted by Comfort, 1979). Statements in recent publications put little distance between cell and organismal finitude: 'Organisms wear out, just like machines' (Ricklefs, 2008); '[D]amage will accumulate in parallel with cells' (Kirkwood, 2005); 'Ageing and its associated decline in survival and reproductive fitness is an inherent feature of biological systems' (Alper, Bronikowski, & Harper, 2015). Studies on ageing focus on a set of cellular and molecular processes that are distinct from those that are the focus of senescence.…”

“…Uno de los principales problemas asociados al envejecimiento es el deterioro del organismo, lo que lo convierte en un factor de riesgo para el desarrollo de diversas enfermedades, incluyendo, diabetes, enfermedades autoinmunes, cardiovasculares, y neurodegenerativas (Venkataraman, 2013) Se reconoce que el envejecimiento produce cambios a todos los niveles de la organización de los seres vivos (Harman, 2003), y está relacionado con un estado físico inadecuado y con un decremento en la supervivencia celular (Alper et al, 2015), en gran medida, debido a los efectos producidos por especies reactivas de oxígeno (ERO).…”

“…(Venkataraman, et al, 2013) Por otro lado, a nivel celular, los fibroblastos se encuentran presentes en cualquier órgano que presente gran cantidad de tejido conectivo. Son células que cumplen funciones de sostén y soporte para otros tipos celulares, y al igual que cualquier otra célula, pueden generar ERO debido al consumo de oxígeno (Alper, et al, 2015), por lo que se han empleado como modelo de estudio de los efectos y respuestas celulares ante el estrés oxidante en relación al proceso de envejecimiento, en distintas especies de mamíferos.…”
