Expand Cell Biology Research with BD Biosciences at ASCB 201...

25-μg and 25-Test Size Reagents To further enable multicolor flow cytometry, BD is introducing small sizes for many of its flow cytometry reagents. These small sizes allow you to cost effectively design and optimize multicolor panel [...]

Tumours bring their own support cells when forming metastase...

The process of metastasis requires that cancer cells travelling from a primary tumour find a hospitable environment in which to implant themselves and grow. A new study from Massachusetts General Hospital (MGH) Cancer Centre researchers [...]

Discovery Halts Breast Cancer Stem Cells

Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell development. Disrupting t [...]

Cell biology: Raiding the sweet shop

Sweetening nectar, maintaining blood sugar levels and producing milk — these are just some of the many processes that require living cells to export sugar. It comes as a surprise, therefore, that until now the identity of the prote [...]

Cell biology: Import and nuclear size

It is rare to come across a basic question in cell biology that is almost entirely unresolved, but what determines the size of a cell or of an organelle is one such question1. Does the cell use a 'molecular ruler' to directly ass [...]

Novel microscope offers intact, high-resolution 3D images of...

German and US scientists have done the seemingly impossible: they have developed a state-of-the-art microscope that delivers an instant three-dimensional (3D) image of intact cells without having to chemically fix, cut or even stain them [...]

Biology in Film: Using Animation to Study Cell Structure

Overview | How can animations help convey the dynamic nature of cellular processes? What can we learn from animation that cannot be learned as easily from still images? In this lesson, students watch high-definition animations that depic [...]

Muscle Mass Doubled by Stem Cell Transplant

Stem cell transplantation into the leg muscles of mice prevented the loss of muscle function and mass that normally occurs with aging, researchers at University of Colorado have said. This is a finding that could be used in treating huma [...]

BIOLOGY: Cell aging mechanism discovered, Salk scientists sa...

Salk Institute scientists say they have discovered a major key to how human and other animal cells age. They have also partly reversed the process in the laboratory, they write in a new study. Damage to vital proteins called histones pla [...]

Faster, Less Damaging Cell Imaging

Recently published research performed at the National Institute of Standards and Technology (NIST) may breathe new life into the use of a powerful, if tricky, diagnostic technique for cell biology. The paper, which is to be presented in [...]
