Provided herein are methods of using tissue culture plastic-adherent placental adherent cells, e.g. placental stem cells, referred to herein as placental adherent cells, to treat lymphedema and lymphedema-related disorders.Provided herein are methods of using tissue culture plastic-adherent placental adherent cells, e.g. placental stem cells, referred to herein as placental adherent cells, to treat lymphedema and lymphedema-related disorders. Described herein are macromonomers, conjugates comprising the macromonomers (also referred to alternatively as "BRUSH", or "BRUSH conjugates"), and brush arm star polymer particles comprising the conjugates (also referred to as "BASPs" or "BASP particles"), each further comprising an agent (e.g., one or more therapeutic agents, diagnostic agents, or targeting moieties), as well as starting materials (e.g., crosslinkers) and other components (e.g., degradation components) thereof, as well as pharmaceutical compositions and methods of making and using the same.En la presente memoria descriptiva se proporcionan métodos para utilizar las células adherentes placentarias que se adhieren al plástico del cultivo de tejido, por ejemplo, las células madre placentarias, referidas en el presente documento como las células adherentes placentarias, para el tratamiento de linfedema y de los trastornos relacionados con el Iinfedema.
