The Living Fossil Psilotum nudum Has Cortical Fibers With Mannan-Based Cell Wall Matrix

open access: yesFrontiers in Plant Science, 2020
Cell wall thickening and development of secondary cell walls was a major step in plant terrestrialization that provided the mechanical support, effective functioning of water-conducting elements and fortification of the surface tissues.

From cell growth to root growth

open access: yesJournal of Theoretical Biology, 1986
The dynamics of root growth is traced back to the growth kinetics of single cells using the concept of the relative elemental rate of elongation (RELEL). In a first step, a formalism for the description of one-dimensional expansion in general is derived with special emphasis on the sigmoid curves which are characteristic for the elongation of single ...

Epidermal Growth Factor Receptor Cell Proliferation Signaling Pathways

open access: yesCancers, 2017
The epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase that is commonly upregulated in cancers such as in non-small-cell lung cancer, metastatic colorectal cancer, glioblastoma, head and neck cancer, pancreatic cancer, and breast ...

Ablation of LRP6 in alpha‐smooth muscle actin‐expressing cells abrogates lung inflammation and fibrosis upon bleomycin‐induced lung injury

open access: yesFEBS Letters, EarlyView.
Low‐density lipoprotein receptor‐related protein 6 (LRP6) is a key receptor for the Wnt antagonist Dickkopf1 (DKK1). DKK1 protein expression is induced in a bleomycin (BLM)‐induced lung injury model. We show that DKK1 induces proinflammatory and profibrotic genes in lung fibroblasts.

BMP2 is Superior to BMP4 for Promoting Human Muscle-Derived Stem Cell-Mediated Bone Regeneration in a Critical-Sized Calvarial Defect Model

open access: yesCell Transplantation, 2013
Muscle-derived cells have been successfully isolated using a variety of different methods and have been shown to possess multilineage differentiation capacities, including an ability to differentiate into articular cartilage and bone in vivo; however ...

Initial cell density encodes proliferative potential in cancer cell populations [PDF]

open access: yesScientific Reports, 2021, 11:6101, 2017
Individual cells exhibit specific proliferative responses to changes in microenvironmental conditions. Whether such potential is constrained by the cell density throughout the growth process is however unclear. Here, we identify a theoretical framework that captures how the information encoded in the initial density of cancer cell populations impacts ...

The expanding role of mTOR in cancer cell growth and proliferation.

open access: yesMutagenesis, 2015
The mechanistic/mammalian target of rapamycin (mTOR) is a conserved protein kinase that controls several anabolic processes required for cell growth and proliferation.

A mathematical model quantifies proliferation and motility effects of TGF--$\beta$ on cancer cells [PDF]

open access: yes, 2008
Transforming growth factor (TGF) $\beta$ is known to have properties of both a tumor suppressor and a tumor promoter. While it inhibits cell proliferation, it also increases cell motility and decreases cell--cell adhesion.

Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

open access: yesFEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Characterization and reduction of non-endocrine cells accompanying islet-like endocrine cells differentiated from human iPSC

open access: yesScientific Reports, 2022
The differentiation of pancreatic endocrine cells from human pluripotent stem cells has been thoroughly investigated for their application in cell therapy against diabetes.
