Zusammenfassung:	ADN COMPLEMENTARIO PREPARADO EXTRAYENDO ARN MENSAJERO DE LAS CELULAS INTERSTICIALES DE LA MEDULA OSEA HUMANA SE EXPRESO, TRAS SER CLONADO, CON LAS CELULAS DE UN MAMIFERO. UNA PROTEINA CON UNA ACTIVIDAD DE INHIBICION DE FORMACION DE ADIPOCITO SE SEPARO DEL CULTIVO CELULAR SUPERNATATIL CON DICHA ACTIVIDAD Y SE PURIFICO. SE OBSERVO QUE LA PROTEINA TENIA UN PESO MOLECULAR APARENTE DE ALREDEDOR DE 23.000 CONDUCIENDO UN ELECTROFORESIS SDS-PAGE BAJO UNA CONDICION REDUCTORA Y QUE TENIA UN RESIDUO DE PROLINA N TERMINAL CON RESULTADO DE IDENTIFICACION DE LA SECUENCIA DE AMINOACIDO N ESTRUCTURA PRIMARIA TOTAL DE LA PROTEINA SE DETERMINO POR EL HALLAZGO ANTERIOR Y EL RESULTADO DE LA CLONACION GENETICA DESCRITA ANTERIORMENTE REVELA QUE ES UNA CITOQUINA CON UNA ACTIVIDAD DE INHIBICION DE FORMACION DE ADIPOCITO Y UNA NUEVA ESTRUCTURA. DE ESTE MODO HA SIDO POSIBLE PRODUCIR UN NUEVO INHIBIDOR DE FORMACION DE ADIPOCITO EN GRANDES CANTIDADES POR LA TECNOLOGIA DE ADN RECOMBINADO ASI COMO DIAGNOSTICAR Y TRATARVARIAS CITOPENIAS Y OTRAS ENFERMEDADES. cDNA prepared by extracting mRNA from the interstitial cells of the human bone marrow was expressed, after being cloned, with the cells of a mammal. A protein having an activity of inhibiting adipocyte formation was separated from the cell culture supernatant having such an activity and purified. The protein was found to have an apparent molecular weight of about 23,000 by conducting SDS-PAGE electrophoresis under a reducing condition and have an N-terminal proline residue as a result of identification of the N-terminal amino acid sequence by Edman degradation. The total primary structure of the protein was determined by the above-mentioned finding and the result of genetic cloning described above to reveal that it is a cytokine having an activity of inhibiting adipocyte formation and a new structure. Thus it has become possible to produce a novel adipocyte formation inhibitor in a large amount by the recombined DNA technology and to diagnose and treat various cytopeniae and other diseases.
