BACKGROUND: The reduced expression of CD10 may be related to unfavorable prognosis of patients with colorectal carcinoma. The authors analyzed the tissue immunostaining of CD10 protein in colorectal carcinoma and its relationship to clinicopathologic features. METHOD: In 130 patients submitted to colorec...
As fraturas e perdas ósseas representam altos riscos para o Sistema público de Saúde (SUS), além de afetar a qualidade de vida do paciente, portanto é necessário o entendimento das bases moleculares que envolvem os mecanismos de reparo ósseo. Citocinas secretadas por células do sistema imune pres...
ANTECEDENTES: Las células pertenecientes a la línea HC11 son estimuladas tanto a proliferar mediante el Factor de Crecimiento Epidérmico, como a diferenciar estimuladas con dexametasona, insulina y prolactina, dando origen a los tipos celulares HC11 GM y HC11 IM, respectivamente. De igual manera cuand...
The present ultrastructural study on developing and regenerating feathers of chick and zebrafinch describes the ultrastructural changes that occur during the differentiation of barb cells that leads to the formation of the ramus of barbs. Differently from barbule and barb cortical cells that accumulate f...
The four main cell functions, proliferation, apoptosis, differentiation and migration, are tightly regulated by external signals that initiate intracellular signal transduction pathways and determine the cellular behaviour. The concentration and composition of such external signals are at least important...
