      Abstract
      Sel natural killer (NK) adalah salah satu sel yang banyak digunakan untuk terapi saat ini, dilaporkan berperan dalam pengobatan tumor dan kanker. Penggunaan sel NK sebagai terapi sel memiliki kemungkinan efek toksik pada organ hati, ginjal, dan limpa. Penelitian bertujuan untuk mengkaji respon jaringan organ hati, ginjal, dan limpa mencit (Mus musculus) terhadap uji toksisitas praklinis xenogenik sel NK manusia melalui analisis kuantitatif histopatologi. Sebanyak sepuluh ekor mencit jantan galur DDY umur 8 minggu dibagi menjadi dua kelompok secara acak. Satu kelompok diinjeksi dengan sel NK manusia dosis 4.112 sel/g BB secara intravena dan kelompok yang lain diinjeksi dengan NaCL fisiologis sebagai kontrol. Mencit kemudian dieuthanasia pada hari ke-14 pasca-injeksi, lalu dinekropsi untuk pengambilan organ dan pembuatan preparat histologi. Seluruh proses histologi dan pengambilan gambar mikroskopis dilakukan pada prosedur dan kondisi yang sama. Pengukuran kuantifikasi data histopatologi menggunakan perangkat lunak ImageJ dan analisis statistik menggunakan perangkat lunak R. Hasil penelitian menunjukkan sitoplasma sel hepatosit mengalami perubahan pH menjadi lebih basa, sel hepatosit tidak mengalami piknosis, sel splenosit limpa didominasi oleh sel immature, serta sel tubular ginjal mengalami piknosis tetapi tidak sampai taraf degenerasi. Hasil ini menunjukkan sel NK manusia tidak memberikan efek toksisitas pada ketiga organ mencit.
       
      Natural killer (NK) cells are widely used for current therapy, reportedly playing a role in the treatment of tumors and cancer. This study aims to find out the effects of human NK cells on mice tissue through the analysis of liver, kidney, and spleen histopathology. Ten male DDY mice aged 8 weeks were randomly divided into two groups. One group was injected with human NK with 4,112 cells/g weight dose intravenously, while the other group was injected with normal saline as a control. Mice were necropsied on the 14th day post-injection, then the liver, kidney, and spleen collected. The organs were made into histology slide and stained with HE. The whole process of histology and microscopic imaging were carried out under the same procedure and conditions. Measurement of quantification of histopathological data using ImageJ software and statistical analysis using R software. The results showed that the cytoplasm of hepatocyte cells underwent a change in pH to become more alkaline, hepatocyte cells did not undergo pyknosis, splenocytes were dominated by immature cells, and kidney tubular cells underwent pyknosis but did not reach degeneration. These results indicate that human NK cells do not have a toxic effect on the three organs of mice.
