(15) Growth plate germinal cell division is directly related to the epiphyseal vascular respect.
(16) Germinal vesicle stage oocytes undergo perinuclear aggregation of acidic organelles during GVBD and these organelles subsequently disperse into the cell cortex as the first meiotic spindle migrates to the oocyte periphery.
(17) When oocytes were microinjected first with the mosxe antisense oligonucleotide, and subsequently with in vitro synthesized v-mos RNA, meiotic maturation was rescued as evidenced by germinal vesicle breakdown.
(18) Effects of alpha- or beta-D-glucose on the respiration of germinated spores (only germinated spores not including swollen spores and elongated spores) of Bacillus subtilis and B. megaterium were studied.
(19) Therefore, Leu 7+ (Leu 3+) germinal-center cells are distinct from "classic" T-helper cells of blood and lymphoid tissues.
(20) Either d- or l-leucine (10(-3)m) and unsaturated long-chain fatty acids such as oleic, linoleic, and arachidonic (10(-4)m) significantly stimulated macroconidia germination of Microsporum gypseum.
Mesoblast
Definition:
(n.) The mesoderm.
(n.) The cell nucleus; mesoplast.
Example Sentences:
(1) The most frequent renal tumor in neonates was the mesoblastic nephroma (3 infants).
(2) Mesoblastic nephroma contained fibronectin but no laminin.
(3) The frequency of mesoblastic nephroma (1%), of bilateral tumors (5%), and of incorrect preoperative diagnosis of Wilms' tumor (5%), the toxicities of the various regimens, and other ancillary data are presented and discussed.
(4) Cytologic diagnosis of mesoblastic nephroma is important because the tumor has an excellent prognosis, and unlike Wilms' tumor, requires only surgery.
(5) In later stages, on human embryos of 11 to 16 mm (37 to 44 days of age; Carnegie stages 16 to 18), the mesoblastic anlage of the appendix is more evident, but it is not invaded by the entoblastic cells which come from the caecum on embryos of 12 to 13 mm.
(6) We have only found eight other reports of adult mesoblastic nephroma.
(7) These results support the hypothesis that a temporary block at some stage in the cell cycle causes mesoblasts to acquire the capacity to differentiate into cartilage cells.
(8) Three main groups are described : ectoblastic, mesoblastic and entoblastic phacomatoses.
(9) These unusual tumors were histologically classified as rhabdoid tumors of the kidney (3 cases) and a cellular mesoblastic nephroma (1 case).
(10) Cellular (or atypical) congenital mesoblastic nephroma (CMN) is a potentially aggressive form of the benign classical congenital mesoblastic nephroma.
(11) Patients 1 and 2 presented during infancy with abdominal masses and hypertension due to bilateral multilocular cysts of the kidney with associated hamartomatous pulmonary cysts; patient 2 also had one area of cellular mesoblastic nephroma.
(12) A case of partially cystic atypical or cellular variant of mesoblastic nephroma in a 27-year old woman is reported.
(13) In contrast to primary mesenchyme or mesoblast, which may form epithelial structures, secondary mesenchyme is incapable of doing so.
(14) The histogenetic relationship to congenital mesoblastic nephroma, Wilms tumor and other tumors is discussed.
(15) The histologic appearance is distinctive and characterized by a marked proliferation of spindled mesenchymal cells resembling the classical type of congenital mesoblastic nephroma, encasing discrete nodules of embryonal epithelium similar to the hyperplastic nephrogenic rests (nephroblastomatosis) usually associated with Wilms' tumor.
(16) However, in view of the possibility of recurrence as shown in rare instances by congenital mesoblastic nephroma, another less aggressive lesion in the spectrum of infantile renal neoplasia, regular follow up is recommended.
