La localizacion de la bomba sodio-potasio ([Na.sup.+]/[K.sup.+]) activa en la membrana basal del trofoblactodermo para transporte ionico activo, esto establece un gradiente que induce movimiento de liquido hacia adentro del blastocele, provocando expansion que hace que las celulas de la morula compactada se ubiquen hacia la zona externa o interna de las vesiculas llenas de liquido, con lo cual se forma una capa celular externa que recibe el nombre de trofoblasto y una masa celular interna llamada embrioblasto, originandose de esta manera el estadio de blastocisto (11); el cual alrededor de los 8 dias de vida posee aproximadamente 120 celulas asociadas con la masa celular interna (embrioblasto) (25%) y el trofoblasto (75%) (1,3).
As a result of chlorpyrifos treatment in this sensitive period, a compact extralarval cap, largely comprised of pigmented cells, formed at the animal pole, and the blastocele, indeed the larva itself, was correspondingly diminished because of both cell extrusion and compaction.
At even lower chlorpyrifos concentrations (2.5-5 [micro]M), there was no extrusion of cells from the blastocele. Instead, the pigmented cells that arose 5-6 hr after addition of chlorpyrifos accumulated inside the larva (Figure 5B), rather than in an external cap.
Some of these embryos remained normal at the mid-blastula 2 stage (category 0), whereas others exhibited anomalies: inhibition of hatching, precocious appearance of mesenchyme cells in the blastocele, and extrusion of some cells to the perivitelline space (Figure 7C, 8A).
The blastocysts shape and the blastocele size were assessed before, 5 and 60 minutes after transfer.
