Predicting the survival rate of mouse embryonic stem cells cryopreserved in alginate beads.

S Sambu et al.

Proceedings of the Institution of Mechanical Engineers. Part H, Journal of engineering in medicine, 225(11), 1092-1107 (2012-02-02)

Stem cell cryopreservation in three-dimensional (3D) scaffolds may offer better protection to cells leading to higher survival rates. However, it introduces heterogeneity in cryoprotective agent (CPA) concentrations, durations of exposure to CPA, and freezing and thawing rate within constructs. This

Effect of alginate encapsulation on the cellular transcriptome of human islets.

Vijayaganapathy Vaithilingam et al.

Biomaterials, 32(33), 8416-8425 (2011-09-06)

Encapsulation of human islets may prevent their immune rejection when transplanted into diabetic recipients. To assist in understanding why clinical outcomes with encapsulated islets were not ideal, we examined the effect of encapsulation on their global gene (mRNA) and selected

Inhalation of alendronate nanoparticles as dry powder inhaler for the treatment of osteoporosis.

Shaheen Sultana et al.

Journal of microencapsulation, 29(5), 445-454 (2012-02-02)

The precipitation technique was used to prepare non-polymeric alendronate nanoparticles. The influence of various formulation parameters on the average particle size was investigated and the effect of various stabilizers (PVA, tween, chitosan, alginate, PEG, HPMC, poloxomers) was evaluated. The selection

Microencapsulated mammalian cells for simultaneous production of VEGF165b and IFNα.

Fatemeh Afkhami et al.

Artificial cells, blood substitutes, and immobilization biotechnology, 40(1-2), 1-6 (2012-02-01)

Targeted and simultaneous delivery VEGF165b and IFN alpha in anti-angiogenic and other applications could offer several advantages. For this a system was design using artificial cell alginate-poly-L-lysine- alginate (APA) microcapsules. Result confirms the ability of this system for simultaneous production
