Throughout their lives, adult Drosophila females continuously produce oocytes, each surrounded by an epithelial monolayer of follicle cells. To characterize the somatic stem cells that give rise to ovarian follicle cells, we marked dividing cells using FLP-catalyzed mitotic recombination and analyzed the resulting clones. Each ovariole in young females contains, on average, two somatic stem cel...

The properties of embryonic hybrid cells obtained by fusion of embryonic stem (ES) or teratocarcinoma (TC) cells with differentiated cells are reviewed. Usually, ES-somatic or TC-somatic hybrids retain pluripotent capacity at high levels quite comparable or nearly identical with those of the pluripotent partner. When cultured in vitro, ES-somatic- and TC-somatic hybrid cell clones, as a rule, l...

Somatic cells are an important component naturally present in milk, and somatic cell count is used as an indicator of udder health and milk quality. The role of somatic cells in dairy processes and products is ill-defined in most studies because the role of these cells combines also the concomitance of physicochemical modifications of milk, bacterial count, and the udder inflammation in the pre...

The ectopic expression of the key transcription factors Oct4, Sox2, c-Myc, and Klf-4 have been shown to reprogram somatic cells to a pluripotent state. In turn these induced pluripotent stem (iPS) cells, like embryonic stem (ES) cells, have been shown to be able to reprogram somatic cells by cell fusion. In this study we compare the differences and similarities between ES and iPS cells measured...

in the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-d) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (camellia sinenesis l.). embryonic axes and cotyledons explants were dissected from the seeds. explants were cultured on murashige and skoog (ms) medium containing 0, 1 and 5 mm 2, 4-d alone for embryonic axes and 0, 1 and 5 mm 2, 4-d along with 0...

BACKGROUND The rate of comorbid depression and medical illness varies from 10 to 40%. Patients with depressive disorder compared to general population more often have cardiovascular and cerebrovascular disorders, diabetes, irritable bowel syndrome, and some types of tumor. Side effects of mental health medications may appear in a form that is very similar to clinical presentation of somatic ill...

ent conccntrations ef 2,4-D, NAA and BAP, large number of somatic cmbryos differentiated When the suspension was cultured for 7 days in the induction medium. The cel]s destined to become somatic embryos divided to form spherical of filamentous proembryos. The fi]amenteus proembryo developed into different shapes of embryos. Somatic embryogenesis began in tlie proembryo stage and preceeded from ...

BACKGROUND Anorexia nervosa is a severe psychosomatic disease with somatic complications in the long-term course and a high mortality rate. Somatic comorbidities independent of anorexia nervosa have rarely been studied, but pose a challenge to clinical practitioners. We investigated somatic comorbidities in an inpatient cohort and compared somatically ill anorexic patients and patients without ...

In the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-D) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (Camellia sinenesis L.). Embryonic axes and cotyledons explants were dissected from the seeds. Explants were cultured on Murashige and Skoog (MS) medium containing 0, 1 and 5 mM 2, 4-D alone for embryonic axes and 0, 1 and 5 mM 2, 4-D along with 0...

Development of a 'gonidialess'/'somatic regenerator' double mutant of Volvox carteri was analyzed with a number of cell-type-specific cDNA probes that had been identified in a previous study. Whereas in wild-type strains somatic cells and gonidia (asexual reproductive cells) constitute two distinct cell lineages, in this mutant all cells first differentiate as somatic cells and then redifferent...
