Comparison of hypoxia (4 % O2) cultured human embryonic stem cells (hESCs) to normoxia (21 % O2) cultured

ABSTRACT: We compared the transcriptome at gene expression level in hypoxic and normoxic conditions. The transcriptome of cells cultured at three different timepoints, 2h, 24 h and 7 days with three different cell lines in normoxia and hypoxia was compared

microRNA expression in primary murine Alveolar type II cells under Normoxia 21% O2 and Hyperoxia 85% O2 after 6 hours and 24 hours

Project description:In this study the microRNA expression of primary murine (C57BL/6) lung alveolar type II cells belonging to four different conditions was analyzed. Effects of hyperoxia 24 hours group were compared to the normoxia 24 hours and effects of the hyperoxia 6 hours group were compared to the normoxia 6 hours.

Gene expression in human umbilical cord vein and artery endothelial cells under physiological chronic normoxia (3% O2, PCN) and standard culture normoxia (21% O2, SCN)

Project description:Endothelial cells, and many other types of cells too, physiologically reside in low O2 environments (~ 2-13% O2 or 15-60 mmHg pO2; [PCN]) relevantly to atmospheric O2 (~ 21% or 160 mmHg pO2 at sea level) in vivo. Such PCN is critical for endothelial functions. The majority of our current knowledge regarding the cellular and signaling mechanisms governing endothelial functions, however, is built on endothelial models established under atmospheric O2 (~21% O2). Herein, we comapred the transcriptional profiles between HUVE and HUAE cells cultured and expanded under PCN (3% oxygen) and standard culture normoxia (21% O2).

Transcriptional profile of Candida parapsilosis CLIB214 21% Oxygen (normoxia) versus at 1% oxygen (hypoxia).

Project description:Whole genome microarray were used to generate the transcriptional profile of C. parapsilosis in hypoxic condition. RNA was isolated from CLIB214 grown in YPD medium in normoxia or hypoxia at 30 degree Celsius for 3.5 h, and labeled with Cy3 or Cy5. Four independent biological replicates were compared. Isolates from normoxic condition were labeled with Cy3 and isolates from hypoxic condition were labeled with Cy5.

Transcriptomes of CD34+ hematopoietic stem/progenitor cells (HSPCs) from myelodysplastic syndromes (MDS) patients cultured in normoxia or hypoxia.

Project description:Three MDS patients (SF3B1mut -H662/H662/Q699) and three age-matched healthy donors were challenged in colony forming assay under normoxic (20% O2) and hypoxic (3% O2) conditions. RNA-sequencing was performed on the HSPC-derived colonies o examine transcriptional changes under normoxic and hypoxic conditions.

Transcription profiles of human dermal papilla cells cultured under 20%-O2 or 6%-O2 condition

Project description:We investigated the effect of low oxygen culture on the proliferation and hair inductive capacity of human dermal papilla cells (DPCs) and dermal sheath cells (DSCs). DPCs and DSCs were cultured in atmospheric/hyperoxia (20% O2), physiological/normoxia (6% O2), or hypoxia (1% O2) conditions, respectively. Proliferation of DPCs and DSCs was highest under normoxia. Hypoxia inhibited proliferation of DPCs but enhanced proliferation of DSCs. In DPCs, hypoxia down-regulated expression of hair inductive capacity-related genes, including BMP4, LEF1, SOX2, and VCAN, and normoxia up-regulated expression of ALP. In DSCs, both normoxia and hypoxia up-regulated SOX2 expression, and hypoxia down-regulated BMP4 expression. Microarray analysis revealed increased expression of pluripotency-related genes, including SPRY, NR0B1, MSX2, IFITM1, and DAZL, under hypoxia. In an in vivo hair follicle reconstitution assay, cultured DPCs and DSCs were transplanted with newborn mouse epidermal keratinocytes into nude mice using a chamber method. In DPCs, normoxia allowed the most efficient induction of hair follicles. In DSCs, hypoxia allowed the most efficient induction and maturation of hair follicles. These results suggest that low oxygen culture enhances the proliferation and maintains functions of human DPCs and DSCs and could be used for skin engineering and clinical applications.
