Haemopoiesis in amphibians has been

Haemopoiesis in amphibians has been studied by
many researchers (e.g. Jordan 1938, Jordan &
Speidel 1923, Maniatis & Ingram 1971, Hadji-
Azimi et al. 1987, Allander & Fry 2008). The de-
velopment of hematopoie
sis in amphibians dis-
plays some similarities to those of birds and
mammals (Allander & Fry 2008). There are great
differences in erythropoiesis between juvenile and
adult amphibians. Erythropoiesis takes place in
the liver and kidney in juvenile amphibians, while
it takes place in the bone marrow as well as in the
spleen and the liver in adult aquatic and terrestrial
frogs. Thyroxine applicatio
n affects erythropoiesis
in adults. In amphibians, ventral blood islets are
the hematopoietic organs in the embryonic period.
Kidneys are also main blood production centres
during the larval periods of amphibian species.
Thymus is the most important place of T-cell
maturation; however, the development place of B-
cells is not completely clear

Haemopoiesis di amfibi telah dipelajari oleh banyak peneliti (misalnya Yordania tahun 1938, Yordania & Speidel 1923, Maniatis & Ingram 1971, Hadji-Azimi et al., 1987, Allander & Goreng 2008). De-velopment dari hematopoiesis in amfibi dis-memainkan beberapa kesamaan bagi burung dan Mamalia (Allander & Goreng 2008). Ada besar perbedaan dalam eritropoiesis antara remaja dan dewasa amfibi. Eritropoiesis mengambil tempat di hati dan ginjal dalam remaja amfibi, sementara itu terjadi di dalam sumsum tulang serta dalam limpa dan hati dalam perairan dewasa dan terestrial katak. Pemberian tiroksin secara application mempengaruhi eritropoiesis pada orang dewasa. Dalam amfibi, Pulau ventral darah yang organ hematopoietik dalam periode embrio. Ginjal adalah juga pusat-pusat produksi darah utama selama periode larva spesies amfibi. Timus adalah tempat paling penting sel T pematangan; Namun, pengembangan tempat B-sel-sel ini tidak sepenuhnya jelas
