2015年1月5日 · In the late cap stage of tooth development, the central cells of the enamel organ have become separated (though maintaining contact by desmosomes), the intercellular spaces containing significant quantities of glycosaminoglycans. The resulting …

2015年1月4日 · At the late cap stage, further folding of the enamel organ establishes future cusp shape as the tooth enters the bell stage. During the bell stage, specific populations of cells differentiate prior to hard tissue formation.

2023年7月25日 · Cap stage: This stage is marked by the growth and expansion of the enamel organ, which results in the formation of a concavity in its inner aspect. The growth continues and at about 12 weeks of intrauterine life i.e., during the late cap stage, inner enamel epithelium forms from the inner cuboidal cells of the enamel organ.
Chapter 8: tooth development – Sheldahl's histology, …
The dental papilla forces the ectoderm of the tooth bud to grow around it, causing the ectoderm of the bud to resemble a cap (a hat), hence the name cap stage. At this time, the dental lamina has two prominent parts—an inner and an outer layer.

2015年1月1日 · By the late cap stage, at 12 weeks of intrauterine life, cells on the inner aspect of the enamel organ change from cuboidal to columnar forming the inner enamel epithelium. The outer layer of cells remains cuboidal and is known as the outer enamel epithelium .
In the late cap stage of tooth development, the central cells of the enlarging enamel organ have become separated (through maintaining contact by desmosomes), the intercellular spaces containing significant quantities of glycosaminoglycans. The resulting tissue is termed the stellate reticulum, although it is not fully developed until the late bell

2012年6月15日 · Our labelling studies also suggest that the dental papilla mesenchyme from E15.5 (late cap stage) is significantly more suitable for studies aiming to target the dental papilla and its derivatives, as the mesenchymal cell population at E15.5 is much larger, more clearly defined and stable compared to earlier stages.
