  • Patent number: 10272053
    Abstract: A method of delivering a compound of interest to the lungs of a subject by the intravenous injection of Sertoli cells loaded with a plurality of chitosan nanoparticles coupled with the compound of interest is provided. Testis-derived rat Sertoli cells were pre-loaded with chitosan nanoparticles coupled with or without the drug curcumin, pre-labeled with a fluorescent cell marker and then injected intravenously into the control or asthmatic mouse model host. Intact pre-loaded, pre-labeled Sertoli cells were present in the lungs at 15 minutes post-injection, appeared entrapped in the pulmonary pre-capillary vascular bed around alveolar sacs but were not present one hour post-injection although Sertoli cell label and cellular debris was. Most of the injected nanoparticle load (70%) and curcumin load (80%) was present in the lungs 15 minutes post-injection, and remained at 70% and 80%, respectively, one hour post-injection.

  • Publication number: 20120148540
    Abstract: The subject invention pertains to tumor cell lines useful for increasing the proliferation potential of any human or animal cell in culture, thereby providing immortalized or continuous cell lines and cultures. The invention also concerns proliferation factors, and compositions containing the factors, which are capable of increasing the proliferation potential of any human or other animal cell in culture. The subject invention further pertains to a method for proliferating cells in culture by contacting cells with the proliferation factors. The proliferated cells can range in plasticity and can include, for example, blast cells, fertilized ova, non-fertilized gametes, embryonic stem cells, adult stem cells, precursor or progenitor cells, and highly specialized cells. Optionally, the cells can be induced to cease proliferation.

  • Patent number: 6037175
    Abstract: A method of enhancing the viability of cryopreserved cells is culturing Sertoli cells in media to produce preconditioned media and adding the preconditioned media to the cells to be cryopreserved. The cells are then cryopreserved. Alternatively, a method of enhancing the viability of cryopreserved cells is co-culturing Sertoli cells and cells to be cryopreserved in media and cryopreserving both.
