Sonic hedgehog protein(SHH) is encoded for by the SHH gene. The protein is named after the character Sonic the Hedgehog.
A morphogen is a substance whose non-uniform distribution governs the pattern of tissue development in the process of morphogenesis or pattern formation, one of the core processes of developmental biology, establishing positions of the various specialized cell types within a tissue. More specifically, a morphogen is a signaling molecule that acts directly on cells to produce specific cellular responses depending on its local concentration.
The Hedgehog signaling pathway is a signaling pathway that transmits information to embryonic cells required for proper cell differentiation. Different parts of the embryo have different concentrations of hedgehog signaling proteins. The pathway also has roles in the adult. Diseases associated with the malfunction of this pathway include cancer.
Flamingo is a member of the adhesion-GPCR family of proteins. Flamingo has sequence homology to cadherins and G protein-coupled receptors (GPCR). Flamingo was originally identified as a Drosophila protein involved in planar cell polarity. Mammals have three flamingo homologs, CELSR1, CELSR2, CELSR3. In mice all three have distinct expression patterns in the brain.
Prickle is also known as REST/NRSF-interacting LIM domain protein, which is a putative nuclear translocation receptor. Prickle is part of the non-canonical Wnt signaling pathway that establishes planar cell polarity. A gain or loss of function of Prickle1 causes defects in the convergent extension movements of gastrulation. In epithelial cells, Prickle2 establishes and maintains cell apical/basal polarity. Prickle1 plays an important role in the development of the nervous system by regulating the movement of nerve cells.
Peter Anthony Lawrence is a British developmental biologist at the Laboratory of Molecular Biology and the Zoology Department of the University of Cambridge. He was a staff scientist of the Medical Research Council from 1969 to 2006.
Planar cell polarity (PCP) is the protein-mediated signaling that coordinates the orientation of cells in a layer of epithelial tissue. In vertebrates, examples of mature PCP oriented tissue are the stereo-cilia bundles in the inner ear, motile cilia of the epithelium, and cell motility in epidermal wound healing. Additionally, PCP is known to be crucial to major developmental time points including coordinating convergent extension during gastrulation and coordinating cell behavior for neural tube closure. Cells orient themselves and their neighbors by establishing asymmetric expression of PCP components on opposing cell members within cells to establish and maintain the directionality of the cells. Some of these PCP components are transmembrane proteins which can proliferate the orientation signal to the surrounding cells.

Philip William Ingham FRS, FMedSci, Hon. FRCP is a British geneticist, currently the Toh Kian Chui Distinguished Professor at the Lee Kong Chian School of Medicine, a partnership between Nanyang Technological University, Singapore and Imperial College, London. Previously, he was the inaugural Director of the Living Systems Institute at the University of Exeter, UK and prior to that was Vice Dean, Research at the Lee Kong Chian School of Medicine.
Norbert Perrimon is a geneticist and developmental biologist at Harvard Medical School. He is known for developing a number of techniques for use of Drosophila, as well as specific substantive contributions to signal transduction and developmental biology. Perrimon co-developed the GAL4/UAS system method, described as “a fly geneticist's Swiss army knife”, with Andrea Brand to control gene expression. With Tze-bin Chou he developed the FLP-FRT DFS method to analyze the maternal effect of zygotic lethal mutations. With Jianquan Ni, he developed and improved methods for in vivo RNAi. His lab has pioneered high-throughput whole-genome RNAi screening.
Elizabeth Jane Robertson is a British developmental biologist based at the Sir William Dunn School of Pathology, University of Oxford. She is Professor of Developmental Biology at Oxford and a Wellcome Trust Principal Research Fellow. She is best known for her pioneering work in developmental genetics, showing that genetic mutations could be introduced into the mouse germ line by using genetically altered embryonic stem cells. This discovery opened up a major field of experimentation for biologists and clinicians.
Athanasia Papalopulu is a Wellcome Trust senior research fellow and Professor of Developmental Neuroscience in the School of Biological Sciences, University of Manchester.
Ruth Lehmann is a developmental and cell biologist. She is the Director of the Whitehead Institute for Biomedical Research, succeeding David Page. She previously was affiliated with the New York University School of Medicine, where she was the Director of the Skirball Institute of Biomolecular Medicine, the Laura and Isaac Perlmutter Professor of Cell Biology, and the Chair of the Department of Cell Biology. Her research focuses on germ cells and embryogenesis.
Evx1 is a mammalian gene located downstream of the HoxA cluster, which encodes for a homeobox transcription factor. Evx1 is a homolog of even-skipped (eve), which is a pair-rule gene that regulates body segmentation in Drosophila. The expression of Evx1 is developmentally regulated, displaying a biphasic expression pattern with peak expression in the primitive streak during gastrulation and in interneurons during neural development. Evx1 has been shown to regulate anterior-posterior patterning during gastrulation by acting as a downstream effector of the Wnt and BMP signalling pathways. It is also a critical regulator of interneuron identity.
