part_of part of part of expresses epithelial cell of proximal tubule CD24-positive, CD-133-positive, vimentin-positive proximal tubular cell 2023-03-07T14:17:39Z CD24-positive tubular cell CD133+CD24+CD106- tubular cell After acute tubular injury, this cell type becomes more numerous. In healthy rat kidneys, this cell is not detectable, whereas after unilateral ureteral obstruction (renal injury), it may appear de novo, arguing against the notion that this cell type represents a pre-existing progenitor cell population. In at least one study, data indicate that this cell type represents transiently dedifferentiated tubular cells involved in regeneration. CD24+CD133+ tubular cell A CD24-positive, CD-133-positive, vimentin-positive cell found scattered throughout a renal proximal tubule and that may participate in tubular regeneration. Compared to other proximal tubular cell types, this cell contains less cytoplasm, fewer mitochondria and no brush border. prominin-1 signal transducer CD24 vimentin proximal tubular epithelium
