Recently, a number of studies have confirmed that ADSCs possess the ability to differentiate into adipocytes, osteoblasts, and chondrocytes [ 16 - 18 ], suggesting that a broader source of stem cells is available for application in tissue engineering. (hindawi.com)
In the next years my lab will focus on determining the molecular mechanisms by which FGF signaling pathways control autophagy in chondrocytes and osteoblasts and on the identification of the physiological roles of autophagy in bone and cartilage. (ectsoc.org)
This, in turn, precipitates chondrocyte apoptosis, thereby, osteoblasts invade the hypertrophic zone and bone formation occurs [ 5 ]. (pfmjournal.org)
Bone tissue is continuously remodeled through the concerted actions of bone cells, which include bone resorption by osteoclasts and bone formation by osteoblasts, whereas osteocytes act as mechanosensors and orchestrators of the bone remodeling process. (taeush.best)
Skeletal tissues, bone, cartilage, muscle and tendon are mechano-responsive tissues consisted of osteoblasts, chondrocytes, myocytes and fibroblasts and their specific extracellular matrices (ECMs). (elsevierpure.com)
Osteoclast differentiation of Pdk4 / bone marrow derived monocyte/macrophage lineage cells from the presence of M CSF and RANKL was suppressed, and osteoclastogenesis was impaired during the coculture of wild form BMMs and Pdk4 / osteoblasts, by which Rankl expression and promoter exercise had been decreased. (jakenzyme.com)
These findings indicate that upregulation of Pdk4 expression in osteoblasts and bone ATP-competitive Caspase inhibitor marrow cells just after unloading is, at the least in element, responsible for the enhancement of osteoclastogenesis and bone resorption soon after unloading. (jakenzyme.com)
PEG MGF increases the proliferation of osteoblasts which are bone mineralizing cells. (muscleandbrawn.com)

The other type of cell that can make you taller are osteoblasts. (enlightenedstates.com)
The field won't just convert your stem cells to chrondocytes, but will also convert them to osteoblasts. (enlightenedstates.com)
The field will make stem cells differentiate into osteoblasts within the bone including the longitudinal ends of the bones (called the subchondral plate). (enlightenedstates.com)
When fully enlarged, chondrocytes are substituted by osteoblasts (the bone builder cells) and their growth plate zone gives place to new bone (Figure 2). (treatingachondroplasia.com)
To identify subpopulations of resting, proliferating, and hypertrophic chondrocytes and osteoblasts involved in bone formation, we have identified here two novel marker genes present in endochondral and intramembranous ossification. (nyu.edu)

Hypertrophic chondrocytes, a progeny of terminally differentiated chondrocytes from the proliferative zone, cease further proliferation, undergo hypertrophy in columns parallel to the axis of longitudinal elongation, and initiate the production of factors that trigger mineralization and vessel invasion. (pfmjournal.org)
Growth hormone (GH), sex hormone, thyroid hormone, as well as glucocorticoids affect chondrocyte proliferation and hypertrophy. (pfmjournal.org)
This supply is very limited and can become insufficient when chondrocytes proliferate and hypertrophy in areas known as growth plates (Figure 1). (mappingignorance.org)

While STAT1 controls the cell's multiplication ( proliferation ) pace , the MAPK pathway is a key controller of the chondrocyte differentiation ( hypertrophy ) pace (Figure 2) (1). (treatingachondroplasia.com)
The key factor to growing taller is the chondrocyte hypertrophy. (enlightenedstates.com)
These stem cells can differentiate into chondrocytes and if these chondrocytes undergo hypertrophy you will grow taller. (enlightenedstates.com)
Also an increase in the hypertrophy rate of these chondrocytes so they work much faster. (enlightenedstates.com)
If you activate these stem cells and these stem cells differentiate into chondrocytes which proceed to hypertrophy then you will grow taller. (enlightenedstates.com)
Upon the influence of these many agents, chondrocytes go from a resting state to a "proliferation frenzy" (multiplication) followed by very significant cell enlargement (what is called hypertrophy ) (Figure 2). (treatingachondroplasia.com)
Chondrocyte hypertrophy is an essential process required for endochondral bone formation. (silverchair.com)
Proper regulation of chondrocyte hypertrophy is also required in postnatal cartilage homeostasis. (silverchair.com)
Indian hedgehog (Ihh) and PTHrP signaling play crucial roles in regulating the onset of chondrocyte hypertrophy by forming a negative feedback loop, in which Ihh signaling regulates chondrocyte hypertrophy by controlling PTHrP expression. (silverchair.com)
To understand whether there is a PTHrP -independent role of Ihh signaling in regulating chondrocyte hypertrophy, we have both activated and inactivated Ihh signaling in the absence of PTHrP during endochondral skeletal development. (silverchair.com)
We found that upregulating Ihh signaling in the developing cartilage by treating PTHrP -/- limb explants with sonic hedgehog (Shh) protein in vitro, or overexpressing Ihh in the cartilage of PTHrP -/- embryos or inactivating patched 1( Ptch1 ), a negative regulator of hedgehog (Hh) signaling, accelerated chondrocyte hypertrophy in the PTHrP -/- embryos. (silverchair.com)
Conversely, when Hh signaling was blocked by cyclopamine or by removing Smoothened ( Smo ), a positive regulator of Hh signaling,chondrocyte hypertrophy was delayed in the PTHrP -/- embryo. (silverchair.com)
Furthermore, we show that upregulated Hh signaling in the postnatal cartilage led to accelerated chondrocyte hypertrophy during secondary ossification, which in turn caused reduction of joint cartilage. (silverchair.com)
Our results revealed a novel role of Ihh signaling in promoting chondrocyte hypertrophy independently of PTHrP , which is particularly important in postnatal cartilage development and homeostasis. (silverchair.com)
In addition, we found that bone morphogenetic protein (Bmp) and Wnt/β-catenin signaling in the cartilage may both mediate the effect of upregulated Ihh signaling in promoting chondrocyte hypertrophy. (silverchair.com)
These mutations cause decreased endochondral ossification, decreased cellular hypertrophy, decreased cartilage matrix production, and inhibited proliferation of chondrocytes in growth plate cartilage. (medscape.com)
