Positive staining of Stro-1 was found in 7.6% of SCAP. Morphologically, PDLSCs were fusiform-shaped, with many short and long ramifications under a scanning electron microscope, and the secreted extracellular matrix were around them.

透射电镜下可见，第1～3代牙周膜干细胞及根尖牙乳头干细胞生长良好，胞浆内线粒体，高尔基体和粗面内质网丰富，随着培养时间的延长，分泌的细胞外基质增多。

We found that during sexual maturation, a low level of SPARC expression occurred in ovary matrix, and moderate in theca cells, but there was no signal in granulosa cells and oocytes.

在eCG诱导的卵泡发育过程中，注eCG 6小时之后，SPARC在卵泡膜细胞和卵巢基质中的表达开始上调，之后显著增强，48小时在膜细胞和卵巢基质中都强表达。

In order to illustrate how soilless growing media to affect growth and bloom of tree peony ,the test on growing mdeia of tree peony was arranged.

为了避免牡丹栽培中土传病虫害的发生与传播，选择牡丹无土栽培基质，我们对牡丹的栽培基质进行了试验研究。

Intimal areas were measured using morphometric analysis of perfusion-fixed vein graft specimens, and intimal thickness was calculated using circumferential measurements. The SMC proliferation was studied by the immunohistochemical detection of proliferating cell nuclear antigen. Expression of MMP-2、MMP-9 mRNA in vein grafts and unoperated control Vein grafts was detected by reverse transcription polymerase chain reaction. Substrate gel zymography was used to determine the proteolytic activity.
