The lung is composed of endoderm derived epithelial cells that constitute the luminal surface of the airways and alveolar spaces. Ensheathing the epithelium are mesenchymal derivatives including airway smooth muscle, pulmonary fibroblasts, and vascular endothelium. During development, the epithelium and mesenchyme are involved in a complex circuit of paracrine and autocrine signals that act to drive morphogenesis and patterning of the developing airway structure. The lung initially arises from the anterior foregut endoderm region, which itself arises from the definitive endoderm that develops soon after gastrulation. .

In response to a signal from the ureter 尿管, mesenchymal cells condense, aggregate into pretubular clusters and undergo an epithelial conversion generating a simple tubule. This then undergoes morphogenesis and is transformed into the excretory system of the kidney, the nephron. We report here that the expression of Wnt-4, which encodes a secreted glycoprotein, correlates with, and is required for, kidney tubulogenesis. Mice lacking Wnt-4 activity fail to form pretubular cell aggregates; however, other aspects of mesenchymal and ureteric development are unaffected. Thus, Wnt-4 appears to act as an autoinducer of the mesenchyme to epithelial transition that underlies nephron development. (Nature . 1994 Dec 15;372(6507):679-83. doi: 10.1038/372679a0.

PMID: 25372631; PMCID: PMC4894444. the genital tubercle, the precursor of the penis and clitoris, arises from two populations of progenitor cells that originate at the lateral edges of the embryo, at the level of the posterior hindlimb buds and anterior tail. During body wall closure, the left and right external genital progenitor pools are brought together at the ventral midline, where they form the paired genital swellings that give rise to the genital tubercle.

Hand-foot-genital syndrome Variants (also called mutations) in the HOXA13 gene cause hand-foot-genital syndrome. The HOXA13 gene provides instructions for producing a protein that plays an important role in development before birth. Specifically, this protein appears to be critical for the formation and development of the limbs (particularly the hands and feet), urinary tract, and reproductive system.

Review Article GLIS1-3: emerging roles in reprogramming, stem and progenitor cell differentiation and maintenance David W. Scoville, Hong Soon Kang, Anton M. Jetten Published: 27 September 2017. doi: 10.21037/sci.2017.09.01 The GLI Similar 1-3 (GLIS) proteins form a subfamily of Krüppel-like zinc finger transcription factors that are closely-related to the GLI and ZIC subfamilies (1–8). Members of these three subfamilies share a highly homologous DNA binding domain (DBD) consisting of five Cys2His2-type zinc finger motifs. However, these proteins exhibit little homology outside their DBD region. … Initial overexpression of OCT3/4 (POU5F1), SOX2, and KLF4 (OSK) are widely used for the reprogramming of somatic cells into iPSCs (32). However, the efficiency of generating iPSCs is very low, which has been attributed to difficulties in overcoming epigenetics barriers in the starting cell (33). Co-expression of C-MYC increases the efficiency, but also enhances the potential tumorigenicity of iPSC-derived differentiated cells. Recently, using a screen analyzing 1,437 transcription factors for their ability to promote reprogramming efficiency, GLIS1 was found to greatly enhance the number of iPSC colonies generated when co-expressed with OSK (referred to as OSKG) in either human or mouse dermal fibroblasts (29,34). Inversely, down-regulation of GLIS1 expression by shRNAs reduced the OSK-induced generation of iPSC colonies in mouse fibroblasts suggesting that endogenous GLIS1 is able to promote OSK-mediated reprogramming.

PMID: 22935022; PMCID: PMC3584308. Later, it was shown that iPS cells can be generated from fibroblasts by viral integration of Oct4/Sox2/Klf4without c-Myc [4]. Although these iPS cells showed reduced tumorigenicity in chimeras and progeny mice, the reprogramming process is much slower, and efficiency is substantially reduced.

The most well known of these enhancer factors is c-Myc, which was added alongside O, S and K in the original reprogramming experiment but later shown to be dispensible [1,5,9,10,15,16].

Somite (Wikipedia) The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the head-to-tail axis in segmented animals. In vertebrates, somites subdivide into the dermatomes, myotomes,sclerotomes and syndetomes that give rise to the vertebrae of the vertebral column, rib cage, part of the occipital bone, skeletal muscle, cartilage, tendons, and skin (of the back).

During vertebrate development, the central (CNS) and peripheral nervous systems (PNS) arise from the neural plate. Cells at the margin of the neural plate give rise to neural crest cells, which migrate extensively throughout the embryo, contributing to the majority of neurons and all of the glia of the PNS. The rest of the neural plate invaginates to form the neural tube, which expands to form the brain and spinal cord.

We have used a retroviral vector encoding enhanced green fluorescent protein to label precursor cells in vivo and have examined clones 1–3 days later using morphological, immunohistochemical and electrophysiological techniques. Here we show that clones consist of mitotic radial glia and postmitotic neurons, and that neurons migrate along clonally related radial glia. Time-lapse images show that proliferative radial glia generate neurons.
成人の脳ではあらたに神経細胞（ニューロン）がつくられることはないと長い間信じられてきて医学部の学部教育でもそう教えられてきましたが、その常識は最近覆りました。脳の一部の領域ではニューロンが成人の脳でも作られていることが発見されたのです。ニューロンが新生する(neurogenesis)領域の一つが海馬で、もうひとつがsubventricular zone (SVZ)と呼ばれる領域です。
Adult neurogenesis, the process of creating new neurons, involves the coordinated division, migration, and differentiation of neural stem cells. This process is restricted to neurogenic niches located in two distinct areas of the brain: the subgranular zone of the dentate gyrus of the hippocampus and the subventricular zone of the lateral ventricle, where new neurons are generated and then migrate to the olfactory bulb.

The squamous part of the temporal bone (or squamous temporalis/squamous temporal bone) is a very thin bone and forms the anterosuperior aspect of the temporal bone. https://radiopaedia.org/articles/squamous-part-of-temporal-bone

Martik, M.L., Bronner, M.E. Riding the crest to get a head: neural crest evolution in vertebrates.Nat Rev Neurosci22, 616–626 (2021). https://doi.org/10.1038/s41583-021-00503-2 無料要旨 In their seminal 1983 paper, Gans and Northcutt proposed that evolution of the vertebrate ‘new head’ was made possible by the advent of the neural crest and cranial placodes. The neural crest is a stem cell population that arises adjacent to the forming CNS and contributes to important cell types, including components of the peripheral nervous system and craniofacial skeleton and elements of the cardiovascular system. In the past few years, the new head hypothesis has been challenged by the discovery in invertebrate chordates of cells with some, but not all, characteristics of vertebrate neural crest cells.
