At birth or after hatching from the egg, vertebrate brains still contain neural stem cells which reside in specialized niches. In some cases, these stem cells are deployed for further postnatal development of parts of the brain until the fi...
Stem cells and lineages of the intestine: a developmental and evolutionary perspective [0.03%]
肠干细胞与谱系的发展和进化视角
Shigeo Takashima,David Gold,Volker Hartenstein
Shigeo Takashima
The intestine consists of epithelial cells that secrete digestive enzymes and mucus (gland cells), absorb food particles (enterocytes), and produce hormones (endocrine cells). Intestinal cells are rapidly turned over and need to be replaced...
The urbilaterian brain revisited: novel insights into old questions from new flatworm clades [0.03%]
revisit bilaterian脑:来自新扁虫类的对旧问题的新见解

Xavier Bailly
Flatworms are classically considered to represent the simplest organizational form of all living bilaterians with a true central nervous system. Based on their simple body plans, all flatworms have been traditionally grouped together in a s...

Planarians are members of the Platyhelminthes (flatworms). These animals have evolved a remarkable stem cell system. A single pluripotent adult stem cell type ("neoblast") gives rise to the entire range of cell types and organs in the plana...
The Hydra FGFR, Kringelchen, partially replaces the Drosophila Heartless FGFR [0.03%]
hydra fgfr kringelchen部分替代果蝇heartless fgfr

Anja Rudolf et al.
Fibroblast growth factor receptors (FGFR) are highly conserved receptor tyrosine kinases, and evolved early in metazoan evolution. In order to investigate their functional conservation, we asked whether the Kringelchen FGFR in the freshwate...
Histological evidence: housekeeping genes beta-actin and GAPDH are of limited value for normalization of gene expression [0.03%]
组织学证据:管家基因β-actin和GAPDH不能用于基因表达的归一化
Juntang Lin,Christoph Redies
Juntang Lin
Housekeeping genes are widely used as internal controls for gene expression normalization for western blotting, northern blotting, RT-PCR, etc. They are generally thought to be expressed in all cells of the organism at similar levels becaus...
Phyllochron dynamics during the course of late shoot development might be affected by reproductive development in rice (Oryza sativa L.) [0.03%]
水稻(Oryza sativa L.)后期茎枝发育过程中由于生殖生长影响其叶龄动态的可能性

Phyllochron, defined as the interval time between appearances of successive leaves on a shoot, is an important measurement to know the developmental state of a shoot apex in rice. Previous studies revealed that phyllochron dynamics during t...
Expression of a cardiac myosin gene in non-heart tissues of developing frogs [0.03%]
蛙非心脏组织中一种心肌肌球蛋白基因的表达

Kimberly Nath
Direct developing frogs, like Eleutherodactylus coqui, provide opportunities to investigate limb early development in anuran amphibians that are less available in species with tadpoles. We have found that myosin heavy chain 6 (myh6), a myos...
Inhibition of the binding of MSG-intermolt-specific complex, MIC, to the sericin-1 gene promoter and sericin-1 gene expression by POU-M1/SGF-3 [0.03%]
POU-M1/SGF-3对MSG滞育特异复合物MIC与蚕丝素基因启动子结合的阻抑及其对丝素基因表达的影响
Mai Kimoto,Tsuyuki Kitagawa,Isao Kobayashi et al.
Mai Kimoto et al.
The sericin-1 gene encoding a glue protein is expressed in the middle silk gland (MSG) of the silkworm, Bombyx mori. A member of the class III POU domain transcription factors, POU-M1, was cloned as the factor bound to the SC site of the se...
The stem cell system in demosponges: suggested involvement of two types of cells: archeocytes (active stem cells) and choanocytes (food-entrapping flagellated cells) [0.03%]
demosponge干细胞系统:两种细胞的参与作用:原细胞(活跃干细胞)和领细胞(摄食纤毛细胞)

Major questions about stem cell systems include what type(s) of stem cells are involved (unipotent/totipotent/pluripotent/multipotent stem cells) and how the self-renewal and differentiation of stem cells are regulated. Sponges, the sister ...
