The lateral cells with endoderm fate (A6.3) also contribute to mesenchyme cells
. These mesenchyme cells
, specifically called trunk lateral cells (TLCs), give rise to adult mesodermal cells including blood cells.
Scanning electron microscopic observations of the mesenchyme cells
in the larvae of the starfish Pisaster ochraceus.
Spicules of the sea urchin embryo are synthesized by primary mesenchyme cells
(PMCs), which are descendants of the micromeres of the 16-cell-stage embryo (Gustafson and Wolpert, 1967; Okazaki, 1975; Ettensohn et al., 1997).
We conclude that, depending on its zinc effect, the Propineb is an effective on the ectoderm cells during the formation of enamel and on the mesenchyme cells
during the formation of dental papilla, as well as causing structural changes, a delay in the development of extracellular matrix, and a recession in dental development.
METHODS: Ar and Esr1 mRNA levels were quantified in primary cultures of fetal mouse prostate mesenchyme cells
treated with [E.sub.2] and BPA.
Three cell recognition changes accompany the ingression of sea urchin primary mesenchyme cells
Total cell number and number of the primary mesenchyme cells
in whole, 1/2 and 1/4 larvae of Clypeaster japonicus.
Beginning at that time, the number of mesenchyme cells
migrating into the blastocele was increased above normal levels.
Therefore, the inductive signal from the endoderm mediated by the same FGF gene results in completely different responses by the recipient cells, namely, increasing the cell division number of the muscle and mesenchyme cells
while restricting the number of the notochord and neural cells.
In euechinoids, there are two types of mesenchyme cells
. The first mesenchyme cells
to ingress are called primary mesenchyme and are derived from the small micromeres that arise at the vegetal pole of the embryo during an unequal fourth cleavage.
were clustered around the wall of this trench (Fig.
Foxb transcription occurs in primary mesenchyme cells
and in the endomesoderm; foxb is regulated by the gene products of brachyury and foxa (Levine and Davidson, 2005).
Within 48 h of bisection, mesenchyme cells
with pseudopodia appeared at the site of bisection (Fig.
