  • Conclusions: This study showed that an osteoblastic cell lineage may be obtained from human bone marrow derived from adherent cells, and that the presence of the rhBMP-4 seems to have an effect during the first stages of differentiation only. (bvsalud.org)
  • In 2010, James Kochenderfer and colleagues achieved a breakthrough with a CAR T cell therapy, reporting tumour regression in a patient with advanced follicular lymphoma, who received two infusions of autologous T cells genetically engineered to express a CAR specifically recognizing the antigen CD19 expressed on B cells. (nature.com)
  • In 2017, two studies - the phase II ZUMA-1 trial led by Sattva Neelapu and a case-series study led by Carl June - validated the efficacy of CD19 CAR T cells in patients with refractory B-cell leukaemia and lymphoma. (nature.com)
