Developmental Dynamics, EarlyView.Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

C-Jun N-terminal kinase (JNK) pathway activation is essential for dental papilla cells polarization.
PLoS ONE, 2021 During tooth development, dental papilla cells differentiate into odontoblasts with polarized morphology and cell function. Our previous study indicated that the C-Jun N-terminal kinase (JNK) pathway regulates human dental papilla cell adhesion ...

Whole Tooth Regenerative Therapy Using a Bioengineered Tooth Germ [PDF]
Current Oral Health Reports, 2013 Dental disorders, including dental caries and periodontal disease, can cause fundamental problems for oral functions, such as enunciation, mastication and occlusion, as well as general health issues. Tooth regenerative therapies for tissue repair and whole tooth replacement are currently being developed as novel treatment approaches.

Dextran sodium sulfate confounds causal role of periodontitis in inflammatory bowel disease
Journal of Periodontology, EarlyView.Abstract Background Emerging evidence supports a bidirectional link between periodontitis and inflammatory bowel disease (IBD). To investigate this relationship, experimental models commonly use dextran sodium sulfate (DSS) to induce colitis. However, DSS is presumed to selectively affect the colon, and its potential off‐target effects on the oral ...

Fusion of a primary mandibular lateral incisor and canine: A rarity
Archives of Medicine and Health Sciences, 2017 Fusion is a developmental anomaly of dental hard tissues characterized by the union of two adjacent teeth. It may be complete with the formation of an abnormally large tooth or incomplete with the union of crowns or roots only.

Prenatal Diagnosis, EarlyView.ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and

Tooth-bone attachment tissue is produced by cells with a mixture of odontoblastic and osteoblastic features in reptiles. [PDF]
J AnatTooth attachment in vertebrates ranges from ligament‐based anchorage in mammals to direct fusion in many reptiles. In the veiled chameleon, we identified a transient cell population—termed ankyloblasts—at the tooth‐bone interface. These cells exhibit both odontoblast‐ and osteoblast‐like features.

Kdf1 Regulates Molar Cusp Morphogenesis via the PI3K/AKT/mTOR Signalling Axis
Cell Proliferation, EarlyView.Epithelial Kdf1 knockout disrupts molar cusp morphogenesis by promoting inner enamel epithelium proliferation and invagination via PI3K/AKT/mTOR signalling. ABSTRACT Keratinocyte differentiation factor 1 (Kdf1) reportedly plays a significant role in enamel formation.
