Advanced Science, EarlyView.Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Defining properties of neural crest-derived progenitor cells from the apex of human developing tooth [PDF]
, 2008 The connective tissue of the human tooth arises from cells that are derived from the cranial neural crest and, thus, are termed as "ectomesenchymal cells." Here, cells being located in a pad-like tissue adjacent to the apex of the developing tooth, which

American Journal of Botany, EarlyView.Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Frontiers in Cell and Developmental Biology, 2022 Dental caries is a common disease that not only destroys the rigid structure of the teeth but also causes pulp necrosis in severe cases. Once pulp necrosis has occurred, the most common treatment is to remove the damaged pulp tissue, leading to a loss of

The use of pulse oximetry in evaluation of pulp vitality in immature permanent teeth [PDF]
, 2016 Background and aim: The current methods of pulp vitality assessment, either electric or thermal, are of limited use in children. Recently, traumatized and immature teeth may not respond to such methods and because such methods require subjective ...

Experimental Biology and Medicine, 1936 Tooth pulps were collected by cracking teeth. Fibrous, calcified and putrescent pulps were discarded. For human teeth, the sample of pulps weighed 0.43 gm. Micro-lipid analyses were carried out using the Bloor oxidative procedures. The total lipids were 0.91% (moist weight), phospholipids 0.70%, and cholesterol 0.11%.

Reassessment of Xenodens calminechari with a discussion of tooth morphology in mosasaurs
The Anatomical Record, EarlyView.Abstract Xenodens calminechari is a mosasaurid taxon named by Longrich et al. (2021) based on the holotype MHNM.KH.331, a left maxilla with several teeth. This holotype was obtained nonscientifically (without technical supervision) from an area in Morocco that yields many manipulated or forged specimens. Examination of Longrich et al.
