The origin of spicule-forming cells in a 'primitive' sea urchin (Eucidaris tribuloides) which appears to lack primary mesenchyme cells
. Development 103: 305-315.
The presumptive notochord cell (B8.6), which is a sister cell of the anterior mesenchyme cell
(B8.5), expresses Brachyury.
In sea urchin larvae, the skeletogenic mesenchyme cells
(4), pigment cells (6), and muscle cells (7) are derived from mesodermal cells, and spatiotemporal and temporal-numeric studies of pigment cells have been conducted in a variety of sea urchin species (8-11).
Abbreviations: PBSC, phosphate-buffered saline saturated with calcite; PMC, primary mesenchyme cell
; SMC, secondary mesenchyme cell
; SW, seawater.
The dental mesenchyme cells
that are condensed around the bud formed the dental papilla between the dental follicles surrounding the epithelium.
Human amnion mesenchyme cells
express phenotypes of neuroglial progenitor cells.
Dermal papilla cell clusters are mesenchyme cells
, which perform several important functions that include being reservoirs of multipotent stem dens, which are critical assets in the area of regenerative medicine; having the physical inductive influence on the cells of undifferentiated epidermis to push into the dermis as part of processes involved in skin appendage formation; acting as body's antidote mechanisms for preventing unwarranted inflammatory reactions; and producing useful antimicrobial proteins.
These fragments very quickly become undistinguishable from other palatal mesenchyme cells
. The epithelia on the nasal aspect of the palate differentiate into pseudostratified ciliated columnar cells while on the oral aspect of the palate differentiate into stratified squamous nonkeratinized cells.
Tubule in cross sections had an irregular shape and some were ruptured, the interstitial tissue contained leydig cells and some lymphocytes with mesenchyme cells
(Fig.1 C, D).In the semi-thin sections, the seminiferous cords appeared solid, containing gonocytes and Sertoli cells (Fig.2 A and B).
OBJECTIVES: We tested the hypothesis that the low-dose effects of estrogens on the developing prostate are associated with increased expression of androgen receptor (Ar) and estrogen receptor 1 ([alpha]) (Esr1) genes in mesenchyme cells
This clearly differs from the spine primordium where the mesenchyme cells
adjacent to the enamel organ had taken the form of what appeared to be a well defined dentine organ prior to any matrix deposition.
