![Fig. 4. Quantification of NGAL and MPO in cells and culture medium by ELISA. NGAL and MPO in undifferentiated (ND) and differentiated (D + RA) cells (▧) and their corresponding media (□) were assayed by ELISA. Release was calculated as the amount of the proteins in medium, given as the percentage of the total amount in medium plus cells. Mean ± SD is given. The secretion of MPO from undifferentiated cells was not significantly different from the secretion of MPO from differentiated cells (difference, 0.9% ± 8.8% [n = 18]), whereas secretion of NGAL from differentiated cells was significantly higher than that from undifferentiated cells (difference, 41% ± 8% [n = 13]).](https://ash.silverchair-cdn.com/ash/content_public/journal/blood/89/6/10.1182_blood.v89.6.2113/3/bl_0025f4.jpeg?Expires=1722765880&Signature=GbETJK8Sr5xmhQEwnPUY2urf6jQ5zWg-~QyRzG0BYWUNRtTWTCcvd~QrZ0jYqeniGR5HUKHsyf8PavELRHRj7S8bbKDEwnMoz4WSJsxdGnbjav6SLK7esqQXeH8E~npx4hvY7bQX8vIXsxRuujkVX3XWe17YS6d62PsLP5ka0Ils5mgBBOHPMI~3zjlf5ilSQwLYF-K35357L~Z2z37xT3Uk8QRgElf2esF~YxWdBLh3iWt1pdoOvw1ZfTgwQQfhYtkJPnivTElJJMTSy9Rb7aloEbRKGgVh9pBbvWhiSioOmFgkDjLS5Xs-L5V808yJk~IJr3SvG8TJ~5fO6SNxuw__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
