Additional bone and cartilage are formed if transforming growth factor-beta is injected into the periosteum of calvariae or long bones. To investigate this further, transforming growth factor-beta 2 was injected into the periosteum of the tibia of 3-day-old, 3-month-old and 2-year-old rabbits. In all instances, there was an increase in proliferation of the cells of the cambial layer of the peri...

Introduction: The quest for finding a regenerative material periodontal defects is everlasting. Numerous resorbable, nonresorbable, synthetic, and autogenous materials have been tried tested in this regard. periosteum has gained popularity field as it exhibited osteogenic properties. harvest of the hassle-free does not cause additional surgical sites. Case Presentation: present case report demo...

Providing a cost-efficient feeding strategy for cell expansion processes remains challenging task due to, among other factors, donor variability. The current method to use fixed medium replacement all batches results often in either over- or underfeeding these cells. In order take into account the individual needs of cells, model predictive controller was developed this work. Reference experime...

statement of the problem this study was designed to investigate the complications after surgical removal of mandibular third molars. patients and methods six hundreds and ninety eight lower third molars among 450 patients surgically extracted by general dentists from april 2005 to april 2006 were selected for this study. data were recorded by completing questionnaires regarding post surgical co...

condylar dislocation is not an uncommon condition and occurs when the condyles are displaced anterior to the articular eminence and are unable to reduce back into the glenoid fossa. long-standing dislocations are difficult to treat with the conservative methods and usually need surgical intervention. in this paper, a long-standing dislocation treated by bilateral extra-oral ramus osteotomy is d...

Periosteum is known to contain cells that, after isolation and culture-expansion, display properties of mesenchymal stromal/stem cells (MSCs). However, the equivalent cells have not been identified in situ mainly due to the lack of specific markers. Postnatally, stem cells are slow-cycling, long-term nucleoside-label-retaining cells. This study aimed to identify and characterise label-retaining...

The activation step of bone remodeling remains poorly characterized. Activation comprises determination of the site to be remodeled, osteoclast precursor recruitment, their migration to the site of remodeling, and differentiation. These actions involve different compartments and cell types. The aim of this study was to investigate events and cell types involved during activation. We used a bone...
