Larval development of the Mexican Snook, Centropomus poeyi (Teleostei: Centropomidae)

open access: yesNeotropical Ichthyology, 2018
We document for the first time the early ontogeny of Centropomus poeyi based on captive raised material representing 0-19 days posthatch (dph). The achievement of early developmental landmarks (i.e., yolk-sac depletion, flexion, development of fins) and ...

Alcam-a and Pdgfr-α are essential for the development of sclerotome-derived stromal cells that support hematopoiesis

open access: yesNature Communications, 2023
The early ontogeny of hematopoietic niches is largely unknown. This article shows that the sclerotome compartment of somites provides Alcam and Pdgfr-α dependent mesenchymal cells that are essential at every step of the development of hematopoiesis.

The ontogeny of sleep-wake cycles in zebrafish: a comparison to humans

open access: yesFrontiers in Neural Circuits, 2013
Zebrafish (Danio rerio) are used extensively in sleep research; both to further understanding of sleep in general and also as a model of human sleep. To date, sleep studies have been performed in larval and adult zebrafish but no efforts have been made ...
