Initial biocompatibility assessments based on lactate dehydrogenase (LDH) assay and morphological examination by SEM with L-929 mouse fibroblasts revealed that CUR-PGNPs@NH2-PVP nanofibrous scaffold was capable of supporting cell growth over a culture period of 3 days.
These calibrations were explained in detail by Fine et al. [ 18], and their phylogenetic placements were determined based on morphological assessments of the fossils relative to living members of the Burseraceae by P. Fine and D. Daly [ 18].
The antibody-based approach allows a morphological assessment to confirm malignancy based on cytomorphological criteria [ 33, 34].
By morphological assessment, tumours are classified based on the cancer cells differentiation into well, moderately and poorly differentiated carcinomas [ 1].
The quantitative approaches to be shown in this paper avoid the pitfalls of empirical morphological assessments, and additionally avoid the problems with pure signal intensity based-measurements which can be confounded by scattering.
The teratogenic potential of compounds can be predicted quantitatively by ranking zebrafish embryos based on a scoring system for phenotypic changes that is conceptually similar to morphological assessments conducted using in vivo embryo-fetal development of mammals [ 15].
Cyclaneusma minus morphotypes can be isolated and cultured from these needles and then identified based on morphological assessment of these cultures.
The percentage of AP-positive cells in a given 60-mm dish was estimated based on the total cell count at D20 of induced differentiation, the number of PGC-like cells estimated to be present in a dish based on morphological assessment, and the number of PGC-like cells that stained positive for AP.
Oocyte maturity was based on morphological assessment [31] where (a) germinal vesicle (GV) stage represented very immature oocyte with a germinal vesicle present, (b) metaphase I (MI) stage oocytes were still immature but the germinal vesicle had disappeared and the first polar body had not been extruded and (c) metaphase II (MII) oocytes were mature and the first polar body was present.
This is also consistent with the reported purities of these mouse spermatocyte and round spermatid fractions (approximately 70 and 90%, repectively, based on morphological assessment [ 46]).
