Summary
Parathyroid hormone (PTH) shows promise for bone regeneration in the craniofacial region and fracture healing. Further research is needed to optimize PTH delivery for enhanced therapeutic outcomes.
Area of Science:
- Bone biology and regenerative medicine
- Craniofacial development and repair
- Endocrinology and skeletal therapeutics
Background:
- Parathyroid hormone (PTH) is recognized for bone-building properties, primarily for osteoporosis treatment.
- Emerging research explores PTH's potential in regenerative applications like fracture healing and oral osseous defects.
- Signaling via the PTH/PTH-related protein receptor (PPR) is crucial for craniofacial bone formation and tooth development.
Purpose of the Study:
- To review the current understanding of parathyroid hormone's role in craniofacial bone regeneration.
- To evaluate the pre-clinical and clinical evidence supporting PTH-based therapies for osseous defects and fracture healing.
- To identify future research directions for optimizing PTH's therapeutic application in regenerative medicine.
Main Methods:
- Review of murine gene-targeted models investigating PTH/PTHrP receptor (PPR) signaling.
- Analysis of pre-clinical studies on intermittent PTH administration in craniofacial bones, fracture healing, and implant integration.
- Evaluation of human clinical studies, including teriparatide use in osteonecrosis of the jaw (ONJ).
Main Results:
- Pre-clinical data strongly support intermittent PTH administration for craniofacial bone healing, fracture repair, and implant success.
- Clinical studies indicate favorable outcomes with teriparatide in patients with osteonecrosis of the jaw.
- New delivery strategies are being developed to enhance targeted PTH application.
Conclusions:
- PTH demonstrates significant potential for craniofacial regeneration and osseous wound healing.
- Further research is essential to define cellular targets, temporal effects, and optimize local delivery methods for PTH.
- Enhanced understanding will improve the efficacy of PTH as a host-modulating agent in regenerative therapies.

00:59The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
00:51Synthesis and Functions of Calcitonin
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

01:18Functions of Thyroid Hormones
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

01:21Skeleton and Calcium Homeostasis
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
