Abstract
Las señales implicadas en el desarrollo fetal del tejido adiposo marrón no se conocen con exactitud. Este trabajo constituye un estudio de los efectos de diferentes factores de crecimiento sobre la proliferación y diferenciación, tanto adipogénica como termogénica, de los adipocitos marrones fetales en cultivo. El estudio se centró en dos factores (el igf-i y el tgf-beta) con un papel bien establecido en relacion con el desarrollo fetal de distintos tejidos, encontrando que ambos estimulan la proliferación y diferenciación de estas células, por lo que se propone al igf-i y al tgf-beta como dos señales que podrían estar implicadas en el desarrollo del tejido adiposo marrón "in vivo"
The signals involved in the fetal development of brown adipose tissue are not known exactly. This work constitutes a study of the effects of different growth factors on the proliferation and differentiation, both adipogenic and thermogenic, of cultured fetal brown adipocytes. The study focused on two factors (igf-i and tgf-beta) with a well-established role in relation to the fetal development of different tissues, finding that both stimulate the proliferation and differentiation of these cells, which is why it is proposed igf-i and tgf-beta as two signals that could be involved in the development of brown adipose tissue "in vivo"
