Developmental biology of lichens [PDF]
New Phytologist, 1993 SUMMARYLichen‐forming fungi are a large, taxonomically diverse group of nutritional specialists which acquire fixed carbon from a population of minute green algal or cyanobacterial cells. Mycobionts of foliose or fruticose lichens differ from the rest of the fungi by expressing morphologically and anatomically complex symbiotic phenotypes.

Quantitative analysis of cell shape and the cytoskeleton in developmental biology
, 2020 Computational approaches that enable quantification of microscopy data have revolutionized the field of developmental biology. Due to its inherent complexity, elucidating mechanisms of development requires sophisticated analysis of the structure, shape ...

Apicosome: Newly identified cell-type-specific organelle in mouse cochlear and vestibular hair cells
iScience, 2023 Summary: Cochlear and vestibular hair cells are highly specialized sensory receptors for hearing and balance. Here, we report a serendipitous identification of a hair-cell-specific organelle in neonatal mouse inner ear, which we name “apicosome.” The ...

Sox9 regulates melanocytic fate decision of adult hair follicle stem cells
iScience, 2023 Summary: The bulge of hair follicles harbors Nestin+ (neural crest like) stem cells, which exhibit the potential to generate various cell types including melanocytes.

Heliyon, 2016 The emerging models of human embryonic stem cell (hESC) self-organizing organoids provide a valuable in vitro platform for studying self-organizing processes that presumably mimic in vivo human developmental events. Here we report that through a chemical

Developmental biology of the meninges [PDF]
genesis, 2019 SummaryThe meninges are membranous layers surrounding the central nervous system. In the head, the meninges lie between the brain and the skull, and interact closely with both during development. The cranial meninges originate from a mesenchymal sheath on the surface of the developing brain, called primary meninx, and undergo differentiation into three

iScience, 2023 Summary: The role of steroid hormone signaling during insect post-embryonic development has been extensively characterized. However, its function during embryonic development is less understood, particularly in short-germ band hemimetabolous insects.

Loss of Fgf9 in mice leads to pancreatic hypoplasia and asplenia
iScience, 2023 Summary: Pancreatic development requires spatially and temporally controlled expression of growth factors derived from mesenchyme. Here, we report that in mice the secreted factor Fgf9 is expressed principally by mesenchyme and then mesothelium during ...
