What's the difference between blastemal and blastematic?
Blastemal
Definition:
(a.) Relating to the blastema; rudimentary.
Example Sentences:

(11) After amputation of the limb of an adult urodele amphibian at any point along the proximodistal axis, blastemal cells (the progenitor cells of the regenerate) give rise only to the missing structures.
(12) The abortive blastems disappear only slowly, because the degeneration of their neoblasts is partly compensated by the continual immigration of new regeneration cells which come from the posterior region.
(13) Such regressions were followed by blastemal formation and middle- to late-bud blastemas were found at the end of 11 or 14 days treatments with retinol palmitate.
(14) Wilms' tumour (nephroblastoma), a childhood embryonal kidney tumour, is believed to arise from malignant transformation of abnormally persistent metanephric blastemal cells.
(15) Blastemal cells from the central portion of the regenerate were observed at varius stages of chrondrogenesis with those immediately beneath the wound epithelium least advanced in this respect.
(16) The molecular weights of the newt proteins detected by these antibodies are very similar to those of human keratins 8 and 18, further supporting the immunocytochemical evidence that the newt homologs of these keratins are expressed in blastemal cells.
(17) To better characterize the cells involved in newt limb regeneration, blastemal cells from accumulation and differentiation phase blastemas were grown in dissociated cell culture, and their morphology and antigenic phenotype determined using a variety of antibodies directed against intermediate filaments, cell adhesion molecules, and extracellular matrix molecules.
(18) However, blastemal cells demonstrated coexpression of CYTO and VIM intermediate filaments when grown in a serum-free medium on a matrix material.
(19) The effects of vitamin A on blastemal epidermis were studied during the early postamputational period of forelimb regeneration in Triturus alpestris.
(20) These observations emphasize the potential value of a monoclonal anti-polysialic acid antibody in identifying blastemal metanephric cells and their epithelial differentiatives in Wilms' tumor.
Blastematic
Definition:
(a.) Connected with, or proceeding from, the blastema; blastemal.
Example Sentences:
(1) We propose that this prostatic primary, nonteratomatous Wilms' tumor can arise from persistent, nephrogenic, blastematous rests in the prostate, in relation to the Wolffian duct system.
(2) The lectin histochemical staining patterns of nine surgically resected Wilms' tumors (WIT) (five classical, one rhabdomyomatous, one monomorphic tubular, and two blastematous) and four WIT heterotransplants in nude mice were compared with those of six normal adult and fetal kidneys using 11 biotinylated and fluorochrome-labeled lectins representing a spectrum of sugar specificities.
(3) This observation recalls the Masson's proposed neuroectodermal histogenesis of Wilms tumor; however the currently accepted metanephrogenic blastematous origin is not reconsidered.
(4) Microscopic examination disclosed blastematous, epithelial, and stromal elements characteristic of Wilms' tumor.
(5) The renal cystadenoma must be regarded as a hamartoma developed from some metanephrogenic blastematous areas excluded from the normal embryogenetic process.
(6) Whereas areas of neural differentiation and occasional argyrophilic cells in cases of Wilms' tumor have been previously reported, the unique characteristic in this case was the extent of the neuroendocrine differentiation, as shown by a strong Grimelius stain of over 90% of the blastematous cells.
(7) Microscopically, the stromal cells resembled blastematous cells seen in Wilms tumor.
(8) In addition, limited reactivity with the neuroblastoma antibodies was seen in blastematous parts of Wilms' tumour, duct-like structures in a hepatoblastoma, and in tumour cells in a few undifferentiated myelo- and lympho-proliferative lesions.
(9) Among the animal tumors, the porcine and canine nephroblastomas showed immunoreactivity for cytokeratin and vimentin in epithelial and blastematous areas, respectively.
(10) Histologically, it consisted of a triphasic tumor; tubular and glomeruloid structures were identified, among prominent blastematous sheets and in an edematous stroma.
(11) Of 60 surgically removed multicystic, dysplastic kidneys examined for the presence of nodular renal blastema only 1 (2 per cent) had blastematous elements.
(12) It derives from the sam blastematic mass as the muscles of mastication, and it is innervated by a branch of the n. mandibularis.
(13) A common histologic feature was the presence of small, primitive cells with blastematous qualities separated by an uncommitted stroma.
(14) The mesenchymal components of blastomas and fetal lung showed smooth muscle, myofibroblastic, and blastematous differentiation.
(15) Histologically, the majority of the tumours (73 per cent) exhibited the classical triphasic morphological features of nephroblastoma (Wilms' tumour) with varying proportions of epithelial (glomeruloid and tubular structures), stromal (fibrous tissue, smooth muscle, cartilage) and blastematous elements.
(16) The blastematous elements demonstrated vimentin and keratin coexpression in four cases, providing some support for the contention that pluripotential blastema may give rise to the epithelial and mesenchymal elements of the distal lobule.
(17) Some axons storing dcv contact blastematic cells and other nerve terminals show a plasma membrane incomplete or broken.
(18) Grossly polypoid on a broad stalk, the neoplasm consisted of a mixture of blastematous, mesenchymal, and epithelial elements.
(19) Microscopically, the tumor masses were hypercellular and anaplastic without definite blastematous elements.
(20) The original WT and first passage xenograft showed a blastematous histology, while the second passage xenograft showed epithelioid differentiation and tubule formation.
