Benzopyrans from Curvularia sp., an endophytic fungus associated with Ocotea corymbosa (Lauraceae)
(2005-10-01)
An isolate of Curvularia sp. was obtained from the leaves of Ocotea corymbosa, a native plant of the Brazilian Cerrado. The ethyl acetate extract from culture of this fungus afforded two benzopyran derivatives: ...
Determining the impact of cell mixing on signaling during development
(Wiley Blackwell Publishing, Inc, 2017-06)
Cell movement and intercellular signaling occur simultaneously to organize morphogenesis during embryonic development. Cell movement can cause relative positional changes between neighboring cells. When intercellular signals ...
Isolation, in vitro study, and stem cell markers for type A spermatogonia in a Characiformes species
(2020-07-01)
The objective of this study was to establish a protocol for the characterization, isolation, and culture of type A spermatogonia using specific molecular markers for these cells in fish. To this end, adult Prochilodus ...
Cortical Tension Allocates the First Inner Cells of the Mammalian Embryo
(Cell Press, 2015-08)
Every cell in our body originates from the pluripotent inner mass of the embryo, yet it is unknown how biomechanical forces allocate inner cells in vivo. Here we discover subcellular heterogeneities in tensile forces, ...
