Analisa Kuantitatif Perubahan Histopatologi Jaringan Hati, Ginjal, dan Limpa Mencit (Mus musculus) setelah Penyuntikan Human Mesenchymal Stem Cells (hMSCs) dan Conditioned Medium(CM)

Abstract

Terapi stem cell menjadi salah satu metode pengobatan baru yang paling menjanjikan untuk mengobati penyakit degeneratif dan iskemik. Human Mesenchymal Stem Cells (hMSCs) dan Conditioned Medium (CM) dapat menghasilkan respon imun. Penelitian ini bertujuan untuk mempelajari respon jaringan hati, ginjal, dan limpa mencit (Mus musculus) melalui gambaran histopatologi setelah diberi hMSCs dan CM melalui vena coccygea. Mencit DDY jantan dengan jumlah 15 ekor dibagi menjadi tiga kelompok perlakuan, kelompok hMSCs, kelompok CM, dan kelompok kontrol yang diinjeksi normal saline. Mencit dinekropsi pada hari ke-14 dan diambil sampel organ untuk difiksasi dengan formalin 10%, kemudian dibuat preparat histopatologi dengan pewarnaan Haematoxylin Eosin (HE) dengan processing yang sama sehingga warna comparable. Gambar histopatologi di analisa secara kuantatif menggunakan aplikasi ImageJ ver. 1.50g dan R software. Hasil penelitian menunjukkan jumlah sel Kupffer menurun yang mengindikasikan tidak adanya inflamasi, hepatosit diduga mengalami regenerasi, luas ruang Bowman kelompok CM menyempit, sel tubulus kelompok hMSCs lebih mature, dan splenosit kelompok hMSCs dan CM immature. Perubahan tidak memperlihatkan adanya respon toksisitas pada jaringan hati, ginjal, dan limpa mencit.

Stem cell therapy is one of the most promising new treatment methods for treating degenerative and ischemic diseases. Human Mesenchymal Stem Cells (hMSCs) and Conditioned Medium (CM) can produce an immune response. This study aims to determine the response of liver, kidney, and spleen tissue of mice (Mus musculus) through histopathology after being given hMSCs and CM through the coccygeal vein. The 15 male DDY mice were divided into three treatment groups, hMSCs, CM, and control injected with normal saline. Mice were necropsied on the 14th day and organ samples were taken to be fixed with 10% formalin, then histopathology preparations were made with Hematoxylin Eosin (HE) staining with the same processing so that the color was comparable. Histopathology images were analyzed quantitatively using the ImageJ app version 1.50 g and R software. The result showed that the number of Kupffer cells decreased which indicated the absence of inflammation, hepatocytes are thought to regenerate, Bowman’s space tightened in the CM group, tubular cells in the hMSCs group were more mature, and splenocytes in the hMSCs and CM groups were immature. The changes did not show any toxic response in the liver, kidney, and spleen tissues of mice.
