This protocol describes the isolation of epithelial cells from different anatomical regions of the human amniotic membrane to determine their heterogeneity and functional properties for possible application in clinical and physiopathological models.

We established the conditions to culture neural progenitor cells from the subventricular zone and dentate gyrus of the adult brain of prairie voles, as a complementary in vitro study, to analyze the sex-dependent differences between neurogenic niches that could be part of functional plastic changes associated with social behaviors.

Here, we present a protocol that can be applied in the neonatal intensive care unit and the delivery room in relation to three scenarios: cardiac arrest, hemodynamic deterioration, or respiratory decompensation. This protocol can be performed with a state-of-the-art ultrasound machine or an affordable handheld device; an image acquisition protocol is carefully detailed.

Pseudomonas aeruginosa produces the rhamnolipid biosurfactants. Thin-layer chromatography detects and determines the proportion of mono- and di-rhamnolipids produced by each strain. Quantification of total rhamnolipids involves assessing rhamnose equivalents present in these biosurfactants extracted from the culture supernatants using the orcinol method.
