IL-4 and TNF induce mAb 6G10-recognized expression on bone marrow stromal cells
Patent Number: 5206345This patent covers a molecule associated with adhesion of cells to the endothelium that is induced by IL-4 and TNF and is recognized by the antibody 6G10 . This molecule may be important in order to alter migration not only of stem cells but also in situations where migration of cells is sought to be avoided such as cancer.

Pharmaceutical composition of BUF-5 for treating anemia
Patent Number: 5200395This patent covers the use of a peptide called BUF-5 for the treatment of anemia. Based on the literature we could not find what exactly BUF-5 is. This could be a very interesting patent for treatment not only of various forms of anemia, but also other hematological diseases in which stimulation of the erythrocyte progenitor is beneficial.

Preparation of pure cultures of post-mitotic human neurons
Patent Number: 5175103This patent covers one of the few stem cell therapies that actually entered clinical trials. The patent is for a teratocarcinoma cell line that is induced to differentiate into neurons with retinoic acid (and/or other factors) and then stops proliferating and can be used for cell therapy in stroke. The technology was eventually developed clinically by Layton Biosciences. Administration of the...
