Over-expression of PPAR-γ2 gene enhances the adipogenic differentiation of hemangioma-derived mesenchymal stem cells and .

Background: Most of infantile hemangiomas involute into fibrofatty tissue in childhood, which indicates adipogenesis during this period. Mesenchymal stem cells (MSCs) contribute to the adipogenesis in IH. In this study, we investigated the effects of overexpression of PPAR-γ2 gene on the adipogenic differentiation of Hemangioma-derived MSCs (Hem-MSCs), and discussed the possibility of targeted therapy via PPAR-γ pathway.

The adipogenesis in infantile hemangioma and the expression of adipogenic-related genes.

Infantile hemangioma, a common benign tumor of infancy, grows quickly in six months to one year after birth, then slowly involutes into fibrofatty tissue childhood. In this study, we observed the adipogenesis in hemangioma and investigated the expression of adipogenic differentiation-related genes. 33 fresh resected hemangioma samples were collected, including 18 proliferating cases (less than one year old), 9 involuting cases (from one to five years old), and 6 involuted cases (more than five years old).

Kasabach-Merritt phenomenon in Chinese children: Report of 19 cases and brief review of literature.

Kasabach-Merritt phenomenon (KMP) is life-threatening, charactered by the profound thrombocytopenia and consumptive coagulopathy associated with vascular tumors. The therapy of KMP still remains challenging. In this study, we retrospectively analyzed the clinical data of KMP treated in Nanjing Children's Hospital and Jinling Hospital, China, and brief reviewed the literature on KMP.

Rosiglitazone accentuates the adipogenesis of hemangioma-derived mesenchymal stem cells induced by adipogenic media.

Hemangioma-derived mesenchymal stem cells (Hem-MSCs) expressed PPAR-γ, the key transcription factor in adipogenesis. We supposed that rosiglitazone, the agonist of PPAR-γ, may promote the adipogenesis of Hem-MSCs. In this study, MSCs were isolated from proliferating hemangioma.

Fiber-optic evanescent wave sensor with a segmented structure.

A segmented structure optic fiber sensor is proposed and demonstrated; it is based on evanescent wave absorption theory. The waveguide modes of the segmented structure are simulated and analyzed by using the beam propagation method, which shows the high-order modes are excited repeatedly at the first transition of each segmented region. The effect of the number of segments and the core diameters on the sensitivity of the sensors is investigated experimentally.

PDGFR-β (+) perivascular cells from infantile hemangioma display the features of mesenchymal stem cells and show stronger adipogenic potential in vitro and in vivo.

Infantile hemangioma, a common benign tumor of infancy, grows quickly in the first year of life, and then regresses slowly to fibrofatty tissue in childhood. The accumulation of fibrofatty tissue in hemangioma involution indicates adipogenesis during this period. Perivascular cells (PCs) from multiple organs display multi-lineage differentiation, including adipogenesis.

Objective: To investigate the treatment of upper lip atrophy resulted by previous therapy.

Methods: From Mar. 2008 to Mar.

Kaposiform hemangioendothelioma complicated by Kasabach-Merritt phenomenon: ultrastructural observation and immunohistochemistry staining reveal the trapping of blood components.

Kaposiform hemangioendothelioma (KHE), a borderline tumor of endothelial origin, is associated with Kasabach-Merritt phenomenon, characterized by profound thrombocytopenia and consumptive coagulopathy resulting from the localized intravascular coagulation (LIC) in the tumor. Previous studies have suggested that the trapping of blood components, including platelets, may underlie the LIC in KHE. However, more evidence is needed to support this hypothesis.

[The role of the expression of PPAR-gamma gene in the adipogenesis in hemangioma evolution].

Objective: To investigate the role of the expression of PPAR-gamma gene in the adipogenesis in hemangioma evolution.

Methods: Routine immunohistochemistry staining of Perilipin A, the marker antigen of adipocytes, was performed to observe the adipogenesis in hemangioma. Immunofluorescence staining of PPAR-gamma, the important transcription factor in promoting adipogenesis, was carried out to observe its location in hemangioma tissue, with the co-staining of alpha-SMA and CD31.

Objective: To discuss the segmental monobloc osteotomy and bi-directional distraction for the treatment of Crouzon syndrome in an infant.

Methods: A 9-month-old female infant underwent monobloc osteotomy through combined intra- and extra-cranial way. The facial skull was divided into frontal, orbital and maxillary segments.

Mesenchymal stem cells in infantile hemangioma reside in the perivascular region.

Infantile hemangioma grows quickly in the first year of life and regresses slowly to fibrofatty tissue during childhood; mesenchymal stem cells (MSCs) have been reported to contribute to this adipogenesis. Recent studies have shown the perivascular origin of MSCs in multiple organs. We hypothesized that MSCs in hemangioma might also reside in the perivascular region.

A novel human error probability assessment using fuzzy modeling.

Human error is one of the significant factors contributing to accidents. Traditional human error probability (HEP) studies based on fuzzy number concepts are one of the contributions addressing such a problem. It is particularly useful under circumstances where the lack of data exists.

Regenerative patterning in Swarm Robots: mutual benefits of research in robotics and stem cell biology.

This paper presents a novel perspective of Robotic Stem Cells (RSCs), defined as the basic non-biological elements with stem cell like properties that can self-reorganize to repair damage to their swarming organization. Self here means that the elements can autonomously decide and execute their actions without requiring any preset triggers, commands, or help from external sources. We develop this concept for two purposes.
