I cannot create a summary of the requested article because the article titled "Autologous versus allogeneic: how cell therapy development is changing in oncology" is not found in the search results provided. The available resources contain information on CAR-T cell therapy, autologous and allogeneic stem cell transplantation in the context of leukemia and lymphoma treatment, but are not excerpts from the specific article you cited. In order to create an accurate and factual summary as per your requirements, I would need access to the full text of this article.
