Answer:
Stellate cells are resident lipid-storing cells of the pancreas and liver that transdifferentiate to a myofibroblastic state in the context of tissue injury. Beyond having roles in tissue homeostasis, stellate cells are increasingly implicated in pathological fibrogenic and inflammatory programs that contribute to tissue fibrosis and that constitute a growth-permissive tumor microenvironment. Although the capacity of stellate cells for extracellular matrix production and remodeling has long been appreciated, recent research efforts have demonstrated diverse roles for stellate cells in regulation of epithelial cell fate, immune modulation, and tissue health. Our present understanding of stellate cell biology in health and disease is discussed here, as are emerging means to target these multifaceted cells for therapeutic benefit.
Answer:
78
Explanation:
Chickens have 78 chromosomes. They inherit 39 from each parent, therefore a zygote (which is made up of an egg and a sperm, each a haploid gamete with 39 chromosomes) will have 78 chromosomes.
This is more than humans: we have 46 chromosomes, as we inherit 23 from each parent.
Respuesta:
B. pastoreo excesivo de animales de granja
Porque son lugares secos.
Explicación:
Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.
