Abstract: Provided herein are methods of using CD10+, CD34?, CD105+, CD200+ tissue culture plastic-adherent placental cells, e.g. placental stem cells, in the treatment of SARS-CoV-2 related acute respiratory failure and ARDS (COVID-19).

Abstract: Provided herein are methods of treating cancer in a human subject comprising administering to the subject an effective amount of CYNK cells to the subject so as thereby to provide an effective treatment of the cancer in the subject. The CYNK cells can be placental-derived natural killer (NK) cells or placental CD34+ cell-derived natural killer (NK) cells. The cancers to be treated include multiple myeloma and acute myeloid leukemia. The present invention also provides compositions comprising CYNK cells for the treatment of multiple myeloma and acute myeloid leukemia and methods of their use.

Abstract: Provided herein are methods of using populations of natural killer (NK) cells and/or ILC3 cells derived from a population of hematopoietic stem or progenitor cells in methods for treating a viral infection, e.g., a coronavirus infection.

Abstract: Provided herein are compositions comprising mononuclear cells from human placental perfusate and methods of using such cells, including using the cells together with hematopoietic cells, for example to establish chimerism, reduce the severity or duration of graft versus host disease, treat or ameliorate symptoms of sarcopenia, metabolic disorders and hematologic disorders, such as hematologic malignancies, and treat or ameliorate symptoms of ischemic encephalopathy (e.g., hypoxic ischemic encephalopathy) and other central nervous system injuries.

Abstract: Provided herein are methods of treatment comprising administering to a subject, e.g., a human subject, mononuclear cells from human placental perfusate and hematopoietic cells, and compositions comprising them, and their uses to establish chimerism, engraft tissue (e.g., blood), reduce the severity or duration of graft versus host disease, and treat or ameliorate symptoms of metabolic disorders and hematologic disorders, such as hematologic malignancies.

Abstract: Provided herein are compositions and methods for treating one or more disorders or conditions in infants, including premature infants, by administering to such infants umbilical cord blood or cells obtained from umbilical cord blood and, optionally, cells obtained from placental perfusate, placental stem cells and/or blood additives. Also provided herein are methods for treating one or more disorders or conditions in infants, including premature infants, by administering to such infants cells obtained from placental perfusate alone or placental stem cells alone or in combination with umbilical cord blood or cells obtained from umbilical cord blood.
