“…While this role has been best documented in the developmental migration of the neural crest and mesoderm, here we expand on previously reported preliminary findings that morpholino knock-down of snai2 impairs the generation of hematopoietic stem cells (HSCs) during zebrafish development. …”

“…The most salient of these features are: short forearm, carpus, and hands, with the radius shorter than the humerus, carpus and manus shorter than the radius (excluding terminal phalanges); a prominent deltopectoral crest that extends distally on the humerus and a wide prominent entepicondyle, a long olecranon process with well-marked attachment of triceps muscle; hooked, laterally compressed, claw-like terminal phalanges with ornamentation of small pits (indicative of well-developed keratin sheaths). …”

“…Here, we show that mice carrying targeted knockin mutations in the corepressor Silencing Mediator of Retinoid and Thyroid hormone receptor (SMRT) that specifically disable SMRT function in NR signaling (SMRT(mRID)), display defects in cranial neural crest cell-derived structures and posterior homeotic transformations of axial vertebrae. …”

“…The ultimobranchial body (UBB) denotes the cellular mass originating from the fourth branchial pouch, which migrates from the neural crest and infolds within the middle and upper poles of the thyroid lobes, thereby establishing the presence of calcitonin-secreting parafollicular C cells. …”

“…In this review, we address the morbidity associated with harvest of the four most commonly used osteocutaneous flaps; the free fibula flap, the scapula flap, the iliac crest flap and the radial forearm flap. A comprehensive literature search was performed to identify articles relevant to donor site morbidity for these flaps. …”

“…CONCLUSION: Primary meningeal melanocytoma of the brain is a rare but benign tumor; the association between meningeal melanocytoma and nevus of Ota is also rare and possibly explained by their common embryonic origin from neural crest cells. There are six cases reported so far in literature including our case for meningeal melanocytoma associated with nevus of Ota.…”

“…The experimental results showed that nano-ZnO/LDPE composites had the advantages such as small crystal size, high crystallization rate and crystallinity owing to nano-ZnO particles doping, when doping nano-ZnO particles size was 30 nm, the ZnO/LDPE nanocomposite crystallinity crest value 39.77% appeared. At the mean time, the DC and AC breakdown field strength values of composites were 138.0 kV/mm and 340.4 kV/mm respectively. …”

“…Results: Mean age was 14,5 years with anterior inferior iliac spine avulsion representing the most common injury (46%), followed by anterior superior iliac spine avulsion (32%), ischial tuberosity avulsion (12%) and iliac crest avulsion (11%). Rates of excellent outcome and return to sports at pre-injury levels were higher after surgical treatment; surgery has a higher risk of heterotopic ossification (9%) compared to conservative treatment (1,8%), whereas the risk of non-unions is lower (0% versus 2,5%). …”
