Fig. 3From: Early immunohistochemical detection of pulmonary micrometastases in dogs with osteosarcomaDistribution and number of micrometastases (cluster of 5–50 TP-3 positive cells) and microscopic metastases (cluster of > 50 TP-3 positive cells) in two dogs with osteosarcoma without macroscopic metastases. a represents case 5 and b represents case 9. Each arrow and box correspond to a specific lung lobe, from the right top side and clockwise: Right cranial lobe, right medial lobe, right caudal lobe, accessory lobe, left caudal lobe, left medial lobe, and left cranial lobe. The solid arrows indicate samples from the peripheral lung tissue, while the dotted arrows indicate samples from the central lung tissue (NE Not examined)Back to article page
