Diversity, Stability, Recursivity, and Rule Generation in Biological System: Intra-inter Dynamics Approach

open access: yes, 1998
Basic problems for the construction of a scenario for the Life are discussed. To study the problems in terms of dynamical systems theory, a scheme of intra-inter dynamics is presented.

Reliable reference genes for expression analysis of proliferating and adipogenically differentiating human adipose stromal cells

open access: yesCellular & Molecular Biology Letters, 2019
Background The proliferation and adipogenic differentiation of adipose stromal cells (ASCs) are complex processes comprising major phenotypical alterations driven by up- and downregulation of hundreds of genes.

Skeletal muscle cells lacking the retinoblastoma protein display defects in muscle gene expression and accumulate in S and G2 phases of the cell cycle. [PDF]

open access: yes, 1996
Viral oncoproteins that inactivate the retinoblastoma tumor suppressor protein (pRb) family both block skeletal muscle differentiation and promote cell cycle progression.

Osteoclast Differentiation [PDF]

open access: yesCritical Reviews in Oral Biology & Medicine, 1991
The osteoclast is the primary bone resorbing cell. It is a highly specialized multinucleated cell whose primary function is to help in the control of calcium homeostasis. The osteoclast has been very difficult to study because of its relative inaccessability, low numbers, and fragility when isolated from bone.

CPM Is a Useful Cell Surface Marker to Isolate Expandable Bi-Potential Liver Progenitor Cells Derived from Human iPS Cells

open access: yesStem Cell Reports, 2015
To develop a culture system for large-scale production of mature hepatocytes, liver progenitor cells (LPCs) with a high proliferation potential would be advantageous.

Automatic Differentiation Variational Inference

open access: yes, 2016
Probabilistic modeling is iterative. A scientist posits a simple model, fits it to her data, refines it according to her analysis, and repeats. However, fitting complex models to large data is a bottleneck in this process.

Fréchet differentiability via partial Fréchet differentiability

open access: yesCommentationes Mathematicae Universitatis Carolinae
Let $X_1, \dots, X_n$ be Banach spaces and $f$ a real function on $X=X_1 \times\dots \times X_n$. Let $A_f$ be the set of all points $x \in X$ at which $f$ is partially Fr\' echet differentiable but is not Fr\' echet differentiable. Our results imply that if $X_1, \dots, X_{n-1}$ are Asplund spaces and $f$ is continuous (resp.

Multi‐layered stochasticity and paracrine signal propagation shape the type‐I interferon response

open access: yesMolecular Systems Biology, 2012
The cellular recognition of viruses evokes the secretion of type‐I interferons (IFNs) that induce an antiviral protective state. By live‐cell imaging, we show that key steps of virus‐induced signal transduction, IFN‐β expression, and induction of IFN ...

Xbra modulates the activity of linker region phosphorylated Smad1 during Xenopus development

open access: yesScientific Reports
The Bmp/Smad1 pathway plays a crucial role in developmental processes and tissue homeostasis. Mitogen-activated protein kinase (Mapk)/Erk mediated phosphorylation of Smad1 in the linker region leads to Smad1 degradation, cytoplasmic retention and ...
