神经胚叶

ABSTRACT Purpose To investigate in clinicopathological features, histogenesis and biological behavior of primary primitive neuroectodermal tumors of cerebrum and spinal cord.

目的：探讨原发于大脑和脊髓原始神经外胚叶肿瘤的临床病理特征、组织学发生及生物学行为。

CCSK is a rare type of renal neoplasm in childhood and its diagnosis relies mainly on histopathology and immunohistochemistry. It is important to be familiar with the morphological variants of CCSK to avoid confusion with other similar lesions, such as Wilm's tumor, congenital mesoblastic nephroma, malignant rhabdoid tumor of kidney, primitive neuroectodermal tumor.

CCSK是一种罕见的儿童期恶性肾肿瘤，诊断主要依靠组织病理学和免疫组化，熟悉其形态学变异有利于与其它类似病变如肾母细胞瘤、先天性中胚叶肾瘤、肾恶性横纹肌样瘤、原始神经外胚叶肿瘤等鉴别。

Here we address this question, focusing on SKPs, a cultured adult stem cell from the dermis that generates both neural and mesodermal progeny.

本文仅就 SKPs 对此问题进行研究， SKPs 是来自皮肤真皮层的一种成体干细胞，该类细胞可以生成神经源性和中胚叶来源的子代细胞。

Results Histologically, AT/RT was characterized by the presence of rhabdoid cells associated with various degrees of primitive neuroectodermal, epithelial or mesenchymal differentiation.

结果 非典型畸胎样／横纹肌样瘤具有特征性的横纹肌样细胞，伴有不同程度的原始神经外胚叶、上皮和间质分化。
