Somatic embryogenesis in cucumber cell suspension culture is a convenient tool to study differential gene expression, particularly during the early stages of this process. In this study, we used the cucumber somatic embryogenesis system to detect genes that were differentially transcribed during the induction of embryo development. We identified and cloned 120 candidate cDNA fragments from differential display gels. The selected cDNAs were confirmed by reverse northern, and 83 were sequenced. The obtained sequences represent 64 independent transcripts. The search for similarities in the databases gave a significant result in 16 cases. The potential involvement of these sequences in somatic embryogenesis is discussed.

Blastoids-blastocyst-like structures created in vitro-emerge as a valuable model for early embryonic development research. Non-human primates stem cell-derived blastoids are an ethically viable alternative to human counterparts, yet the low formation efficiency of monkey blastoid cavities, typically below 30%, has limited their utility. Prior research has predominantly utilized embryonic stem cells.

The heterogeneity of ovarian mesenchymal/stromal cells has just been revealed in both mice and humans. However, it remains unclear about the cellular development trace and the intercellular communication network in the whole life of the ovary. In the study, we integrated ours and published single-cell RNA sequencing data from E11.

A time-lapse live embryo monitoring system provides a powerful approach to recording dynamic developmental events of cultured embryos in detail. By obtaining continuous short-interval images, blastocyst formation can be predicted and embryos can be selected. The objective of this study was to investigate the morphokinetic parameters of fishing cat-domestic cat interspecies somatic cell nuclear transfer (iSCNT) embryos from one-cell to blastocyst stages, and in particular, the cleavage patterns of the first division in iSCNT and IVF embryos, as these play a central role in euploidy.

Background/objectives: (ALS), or Lou Gehrig's disease, is a debilitating, incurable neurodegenerative disorder characterised by motor neuron death in the spinal cord, brainstem, and motor cortex. With an incidence rate of about 4.42 cases per 100,000 people annually, ALS severely impacts motor function and quality of life, causing progressive muscle atrophy, spasticity, paralysis, and eventually death.

Background: Spermatogenesis is a complex process of cellular differentiation that commences with the division of spermatogonia stem cells, ultimately resulting in the production of functional spermatozoa. However, a substantial gap remains in our understanding of the molecular mechanisms and key driver genes that underpin this process, particularly in invertebrates. The dwarf surfclam (Mulinia lateralis) is considered an optimal bivalve model due to its relatively short generation time and ease of breeding in laboratory settings.
