ABSTRACT
The objective of this study was to evaluate the development of transgenic (T) goat embryos and fetuses for human Granulocyte Colony Stimulating Factor (hG-CSF) by ultrasonography. Four pregnancies in non-transgenic (NT) goats were obtained after fertilization (either fixed-time artificial insemination or natural mating) using the T male for hG-CSF. Ultrasound examinations were carried out at 30, 40 (transrectal via), 50, 60, 90 and 120 days of pregnancy (transabdominal via). Some parameters were observed such as morphology, organogenesis and formation of skeletal fetuses, viability with cardiac activity and fetuses movements. Measurements were taken of the crown-rump length, diameter of embryonic vesicle, thorax, abdomen, umbilical cord and placentomes. After parturition, DNA testing was conducted in all offspring and 4 T and 2 NT kids were identified. The conceptus started their differentiation at 40 days. The heart was detected in all examinations and the heart chambers were assessed at 50 days. Gastric compartments, liver and kidneys were observed at 60 days, the same period that all bony structures were visualized. Average values of all evaluated parameters had a gradual increase with the progression of pregnancy. T and NT goat embryos and fetuses had a similar growth and all remained viable throughout the experimental period.
RESUMO
O objetivo deste estudo foi avaliar o desenvolvimento de embriões e fetos transgênicos (T) para o Fator Estimulante de Colôniasde Granulócitos humano (hG-CSF) por ultrassonografia. Quatro gestações em cabras não transgênicas (NT) foram obtidas pos fecundação (inseminação artificial em tempo fixo ou monta controlada) utilizando o bode T para o hG-CSF. Exames ultrassonográficos foram realizados aos 30, 40 (via transretal), 50, 60, 90 e 120 dias de gestação (via transabdominal). Alguns parâmetros foram observados como morfologia, organogênese e formação do esqueleto fetal, viabilidade por meio de atividade cardíaca e movimento fetal. As seguintes mensurações foram realizadas comprimento crânio caudal, diâmetro da vesícula embrionária, do tórax, do abdomen, do cordão umbilical e dos placentomas. Após o parto, o exame por PCR foi conduzido em todas as crias e 4 T e 2NT foram identificadas. O concepto iniciou sua diferenciação aos 40 dias. O coração foi detectado em todos os exames e as câmeras cardíacas foram identificadas aos 50 dias. Compartimentos gástricos, fígado e rins foram observados aos 60 dias, o mesmo período que todas as estruturas ósseas foram visualizadas. Valores médios de todos os parâmetros avaliados tiveram um aumento gradual com o avanço da gestação. Embriões e fetos T e NT tiveram um crescimento similar e todos permaneceram viáveis durante o período experimental.
