Highly conserved and extremely evolvable: BMP signalling in secondary axis patterning of Cnidaria and Bilateria [0.03%]
高度保守而又极其易变：BMP信号在Cnidaria和Bilateria次生轴模式中的作用

Bilateria encompass the vast majority of the animal phyla. As the name states, they are bilaterally symmetric, that is with a morphologically clear main body axis connecting their anterior and posterior ends, a second axis running between t...
Nerves and availability of mesodermal cells are essential for the function of the segment addition zone (SAZ) during segment regeneration in polychaete annelids [0.03%]
多毛纲环节动物节段再生过程中神经和中胚层细胞的可用性对节段增殖区(SAZ)功能至关重要

Most of annelids grow all over their asexual life through the continuous addition of segments from a special zone called "segment addition zone" (SAZ) adjacent to the posterior extremity called pygidium. Amputation of posterior segments lea...
Advances in genome sequencing reveal changes in gene content that contribute to arthropod macroevolution [0.03%]

Current sequencing technology allows for the relatively affordable generation of highly contiguous genomes. Technological advances have made it possible for researchers to investigate the consequences of diverse sorts of genomic variants, s...
From "self-differentiation" to organoids-the quest for the units of development [0.03%]
从自我分化到类器官——探寻发育单位之谜

Gerhard Schlosser
As proposed by Wilhelm Roux in 1885, the key goal of experimental embryology ("Entwicklungsmechanik") was to elucidate whether organisms or their parts develop autonomously ("self-differentiation") or require interactions with other parts o...
Central projections from Johnston's organ in the locust: Axogenesis and brain neuroarchitecture [0.03%]
Johnston器的中心投射：轴突发生和脑神经结构
George Boyan,Leslie Williams,Erica Ehrhardt
George Boyan
Johnston's organ (Jo) acts as an antennal wind-sensitive and/or auditory organ across a spectrum of insect species and its axons universally project to the brain. In the locust, this pathway is already present at mid-embryogenesis but the p...
Effect of overexpression of KLF4 on the growth and development of hair follicles in mice [0.03%]
KLF4过表达对小鼠毛囊生长发育的影响

Hongyu Han et al.
Hair follicle growth is cyclical, and hair cycle dysfunction can lead to hair follicle-related disorders, including alopecia and hirsutism. The objective was to investigate the influence and underlying mechanism of Krüppel-like factor 4 (K...
The genomic landscape of mammal domestication might be orchestrated by selected transcription factors regulating brain and craniofacial development [0.03%]
哺乳动物驯化的基因组特征或许是由选择性调控大脑和颅面发育的转录因子决定的

Domestication transforms once wild animals into tamed animals that can be then exploited by humans. The process entails modifications in the body, cognition, and behavior that are essentially driven by differences in gene expression pattern...
Expression of posterior Hox genes and opisthosomal appendage development in a mygalomorph spider [0.03%]
独行蛛后HOX基因的表达及末体附肢发育关系研究

Spiders represent an evolutionary successful group of chelicerate arthropods. The body of spiders is subdivided into two regions (tagmata). The anterior tagma, the prosoma, bears the head appendages and four pairs of walking legs. The segme...
Expression of 20 SCPP genes during tooth and bone mineralization in Senegal bichir [0.03%]

S Delgado et al.
The African bichir (Polypterus senegalus) is a living representative of Polypteriformes. P. senegalus possesses teeth composed of dentin covered by an enameloid cap and a layer of collar enamel on the tooth shaft, as in lepisosteids. A thin...
