Description:
Therapeutic Progesterone is a synthetic form of the endogenous hormone progesterone. Progesterone binds to the progesterone receptor, resulting in dissociation of heat shock proteins, receptor phosphorylation, and transcription activation through direct or indirect interaction with transcription factors. This agent exerts inhibitory effects on estrogens by decreasing the number of estrogen receptors and increasing its metabolism to inactive metabolites. Progesterone induces secretory changes in the endometrium, decreases uterine contractility during pregnancy, and maintains pregnancy. (NCI04)

Progesterone is a Progesterone. The chemical classification of progesterone is Progesterone.
from FDA Pharm Classes
Progesterone is a C21-steroid hormone in which a pregnane skeleton carries oxo substituents at positions 3 and 20 and is unsaturated at C(4)-C(5). As a hormone, it is involved in the female menstrual cycle, pregnancy and embryogenesis of humans and other species. It has a role as a contraceptive drug, a progestin, a progesterone receptor agonist, a human metabolite and a mouse metabolite. It is a 20-oxo steroid, a 3-oxo-Delta(4) steroid and a C21-steroid hormone. It derives from a hydride of a pregnane.

<span>The question makes it seem that you looked through both types of microscopes at specific samples? As for how they would differ, a light microscope's level of magnification is limited by the physical characteristics of light and therefore can only see objects as small as organelles inside of a cell. A scanning electron microscope, however, does not use light, it uses a beam of electrons to visualize the sample. Electrons are much smaller than the light beam and are able to image much smaller objects, such as molecules and atoms.</span>
