Correction

Based on inaccurate figures on the stem cell agency web site, the NIH/CIRM sickle cell item on Oct. 9,2018, incorrectly reported that the agency had committed more than $200 million to sickle cell research. The correct amount is $38.8 million. CIRM said that the error was created by a computer glitch and that it has corrected the figures on its site. The item has also been corrected.
