We integrated ubiquity, mass and lifespan of all major cell types to achieve a comprehensive quantitative description of cellular turnover. We found a total cellular mass turnover of 80 ± 20 grams per day, dominated by blood cells and gut epithelial cells. In terms of cell numbers, close to 90% of the (0.33 ± 0.02) × 10¹² cells per day turnover was blood cells.

人体细胞更新分布

我们整合了所有主要细胞类型的普遍性、质量和寿命，以实现对细胞更新的全面定量描述。我们发现每天的总细胞质量周转量为 80 ± 20 克，主要是血细胞和肠上皮细胞。就细胞数量而言，接近 90% 的 (0.33 ± 0.02) × 10 ¹²细胞/天周转是血细胞。
