Spanish to English Medical Medical (general) Pneumology

Hi again, still working on the abstract.

Now I ran into this term in the following sentence:

Las evaluaciones inmunohistoquímicas comparativas entre grupos muestran expresiones diferenciadas en los componentes del tejido pulmonar: estroma, alveolo, mesénquima para captación de las señales de factores involucrados en el crecimiento pulmonar: factor de crecimiento epidermal, factor de crecimiento derivado de las plaquetas y factor transformador de crecimiento beta.

My try (feel free to provide corrections to any other terms I may have translated mistakenly):

Comparative immunohistochemical evaluations among groups show differentiated expressions within lung tissue components: stroma, alveoli, mesenchyme to seize signals of factors involved in pulmonary growth: epidermal growth factor, platelet-derived growth factor and beta growth transformation factor.
