In humans, what muscle is homologous to the serratus ventralis found in cats
Nat2105 [25]
The Serratus anterior in man is homologous to the Serratus ventralis  muscle in the cat. The Serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and insects along the entire anterior length of the medial border of the scapula. The Serratus anterior acts to pull the scapula forward around the thorax. Serratus ventralis in the cats looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs.

Investiga como se reproducen las células madres​
Damm [24]

Answer:

Las células madre son células que se reproducen constantemente y tienen la capacidad de transformarse en cualquier otro tipo de célula del cuerpo de un organismo. Una célula a partir de la cual pueden crecer todos los tejidos del cuerpo, o una gran parte de ellos, es obviamente una célula extremadamente útil.  

Si las células madre se guían en la formación de tejidos sanos y funcionales, entonces, potencialmente, la terapia celular podría aplicarse para muchas enfermedades. De hecho, si las células provienen del propio paciente, en teoría no habrá riesgo de su rechazo (como lamentablemente ocurre con los trasplantes).

Las células madre tienen la capacidad de reproducirse por sí mismas a través del proceso de mitosis celular, para crear copias idénticas (clones) de sí mismas..
