The developmental cell biology of Trypanosoma brucei [PDF]
, 2005 Trypanosoma brucei provides an excellent system for studies of many aspects of cell biology, including cell structure and morphology, organelle positioning, cell division and protein trafficking. However, the trypanosome has a complex life cycle in which

Isolating and Quantifying the Role of Developmental Noise in Generating Phenotypic Variation [PDF]
, 2018 Genotypic variation, environmental variation, and their interaction may produce variation in the developmental process and cause phenotypic differences among individuals. Developmental noise, which arises during development from stochasticity in cellular

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

Feto-maternal microchimerism: Memories from pregnancy
iScience, 2022 Summary: There is a bidirectional transplacental cell trafficking between mother and fetus during pregnancy in placental mammals. The presence and persistence of fetal cells in maternal tissues are known as fetal microchimerism (FMc).

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

Genes Classical And Genes Developmental: The Different Uses Of The Gene In Evolutionary Synthesis [PDF]
, 2000 Dobzhansky (1964) stated that “Nothing in biology makes sense except in the light of evolution,” and the function of the gene is no exception. The use of genes in population genetics and developmental genetics differs significantly.

Brown adipocytes can display a mammary basal myoepithelial cell phenotype in vivo [PDF]
, 2017 This work was supported by the Strategic Priority Research Program of the Chinese Academy of Sciences (XDB13030000) and the CAS-Novonordisk Foundation, as well as grants from the ‘1000 talents’ recruitment program, and a ‘Great-wall professorship’ from ...

miR-29cb2 promotes angiogenesis and osteogenesis by inhibiting HIF-3α in bone
iScience, 2022 Summary: Coordination between osteogenesis and angiogenesis is required for bone homeostasis. Here, we show that miR-29cb2 is a bone-specific miRNA and plays critical roles on angiogenesis-osteogenesis coupling during bone remodeling.

Philosophy of Developmental Biology
, 2022 The history of developmental biology is interwoven with debates as to whether mechanistic explanations of development are possible or whether alternative explanatory principles or even vital forces need to be assumed. In particular, the demonstrated ability of embryonic cells to tune their developmental fate precisely to their relative position and the
