Autier et al. (2019)8 have developed a bacterial cellulose implant loaded with human serum albumin (HAS), whereas a recent study evaluated the capacity of the chemoattractant CXCL12 to attract residual glioblastoma stem cells into a thiol-Michael hydrogel, confirming the specific attraction of GBM cells into the gel.9 The gene discussed is ALB; the disease is glioblastoma.
