Although haemoglobin is a known carrier of oxygen in erythrocytes that functions to transport oxygen over a long range, its physiological roles outside erythrocytes are largely elusive1,2. Here we found that chondrocytes produced massive amounts of haemoglobin to form eosin-positive bodies in their cytoplasm. The haemoglobin body (Hedy) is a membraneless condensate characterized by phase separation. Production of haemoglobin in chondrocytes is controlled by hypoxia and is dependent on KLF1 rather than the HIF1/2α pathway. Deletion of haemoglobin in chondrocytes leads to Hedy loss along with severe hypoxia, enhanced glycolysis and extensive cell death in the centre of cartilaginous tissue, which is attributed to the loss of the Hedy-controlled oxygen supply under hypoxic conditions. These results demonstrate an extra-erythrocyte role of haemoglobin in chondrocytes, and uncover a heretofore unrecognized mechanism in which chondrocytes survive a hypoxic environment through Hedy.

BriefingWire.com, 4/09/2021 - Global slide stainers market was valued US$ 2.68 Bn in 2017 andis expected to reach US$ 6.1 Bn by 2026, at a CAGR of 10.83 % during a forecast period.
Stain is a substance used to give color to tissues & cells and to facilitate microscopic study & identification. Slide stainers automate the staining of prepared cytology & histology tissue samples by diffusing tints into the samples through surface adsorption, direct staining, indirect staining, and mordant staining.
