Expression of FET-1 related transcripts during chicken embryogenesis suggests a role in muscle development.

The genetic basis of somatic cell identity in avian sex determination is still unknown. FET1, an endogenous retrovirus, has previously been demonstrated to be expressed during gonad development. Here, we report expression of FET1 related transcripts in non-gonadal tissue during chicken development.

Fgf17: A regulator of the mid/hind brain boundary in mammals.

The Fibroblast growth factor (FGFs) family consists of at least 22 members that exert their function by binding and activating fibroblast growth factor receptors (FGFRs). The Fgf8/FgfD subfamily member, Fgf17, is located on human chromosome 8p21.3 and mouse chromosome 14 D2.

Data-Driven and Cell-Specific Determination of Nuclei-Associated Actin Structure.

Quantitative and volumetric assessment of filamentous actin fibers (F-actin) remains challenging due to their interconnected nature, leading researchers to utilize threshold based or qualitative measurement methods with poor reproducibility. Here we introduce a novel machine learning based methodology for accurate quantification and reconstruction of nuclei-associated F-actin. Utilizing a Convolutional Neural Network (CNN), we segment actin filaments and nuclei from 3D confocal microscopy images and then reconstruct each fiber by connecting intersecting contours on cross-sectional slices.

Early postnatal development of the primary visual areas 17 and 18 of the cat cerebral cortex: An SMI-32 study.

Using anti-neurofilament H non-phosphorylated antibodies (SMI-32) as markers for the neuronal maturation level and Y channel responsible for motion processing, we investigated early postnatal development of the primary visual areas 17 and 18 in cats aged 0, 10, 14, and 34 days and in adults. Two analyzed parameters of SMI-32-immunolabeling were used: the total proportion of SMI-32-labeling and the density of labeled neurons. (i) The developmental time course of the total proportion of SMI-32-labeling shows the general increase in the accumulation of heavy-chain neurofilaments.
