求翻译：大鼠胰岛大部分细胞及部分胰腺外分泌部细胞呈FSH和FSHR免疫荧光反应阳性，阳性物质分布于细胞质，细胞核呈阴性反应是什么意思？

Most of rat pancreatic islet cells and exocrine part of the pancreas cells was of fsh and fshr immunofluorescence reaction positive, positive material distributed in the cytoplasm, the nucleus was negative

The mouse Langerhans cells and most part of Pancreatic secretion, and cell is FSH FSHR immunization fluorescent positive, positive material distribution in the cell nucleus, and quality are negative

The big mouse island of langerhans majority of cells and the partial pancreatic gland exocrine department cell assumes FSH and the FSHR immunity fluorescence response masculine gender, the masculine material distributes in the cytoplasm, the cell nucleus assumes the negative reaction

Most of rat islet cells and partial pancreas exocrine cells FSH and FSHR immuno-fluorescence-positive, positive material distributed in the cytoplasm, nuclei are negative
