ABSTRACT
Efforts have been made to establish various human pluripotent stem cell lines. However, such methods have not yet been duplicated in non-human primate cells. Here, we introduce a multiplexed single-cell sequencing technique to profile the molecular features of monkey pluripotent stem cells in published culture conditions. The results demonstrate suboptimized maintenance of pluripotency and show that the selected signaling pathways for resetting human stem cells can also be interpreted for establishing monkey cell lines. Overall, this work legitimates the translation of novel human cell line culture conditions to monkey cells and provides guidance for exploring chemical cocktails for monkey stem cell line derivation.

Objective To evaluate the diagnostic value of MRI for the mammographic sign of focal asymmetry of the breast (FAB) .Methods The morphological features of MRI and Time‐signal intensity curve (TIC) types of 46 cases of mammographic signs of FAB were analyzed retrospectively .Results In all 46 patients ,MRI detected 46 lesions in the corresponding areas of FAB on mammography ,in which 35 cases of benign lesions and 11 cases of malignant lesions were confirmed by pathology .The accuracy , positive predictive value and negative predictive value of the sub‐leaf shape and edge burr of the breast lesions were 82 .61% ,66 .67% , 86 .49% and 86 .96% ,85 .71% ,87 .18% respectively .TIC showed:in type Ⅰ ,all 17 cases were benign;In type Ⅱ ,4 cases were be‐nign and 2 cases were malignant ;In type Ⅲ ,9 cases were all malignant .The diagnostic accuracy of MRI for the benign and malignant breast lesions was 86 .96% .The positive predictive value and negative predictive values were 81 .82% and 96 .88% respectively .Con‐clusion MRI can definitely estimate the potential character of lesion in FAB ,and more accurately discriminate malignant and benign breast lesions .
