Fig. 1From: Wnt3a nanodisks promote ex vivo expansion of hematopoietic stem and progenitor cellsModel depiction of a Wnt ND. When combined, phospholipid and apoA-I interact to form discoidal rHDL complexes. When this reaction proceeds in the presence of Wnt3a, its covalently bound fatty acid is postulated to insert into the ND bilayerBack to article page
