Mathiasen AB, Hansen L, Friis T, Thomsen C, Bhakoo K, Kastrup J.
PMID: 23577035
Stem Cells Int. 2013;2013:353105. doi: 10.1155/2013/353105. Epub 2013 Mar 19.

Background. Regenerative therapy is an emerging treatment modality. To determine migration and retention of implanted cells, it is crucial to develop noninvasive tracking methods. The aim was to determine ex vivo magnetic resonance imaging (MRI) detection limits of ultrasmall...

American journal of nuclear medicine and molecular imaging

Tietz O, Kamaly N, Smith G, Shamsaei E, Bhakoo KK, Long NJ, Aboagye EO.
PMID: 23901361
Am J Nucl Med Mol Imaging. 2013 Jul 10;3(4):372-83. Print 2013.

The G-protein coupled C-X-C chemokine receptor type 4 (CXCR4) is highly overexpressed in a range of cancers and is therefore an excellent biomarker for cancer imaging. To this end targeted iron oxide nanoparticles were developed and utilised for in...

Bone marrow mesenchymal stem cells with low dose bone morphogenetic protein 2 enhances scaffold-based spinal fusion in a porcine model.

Journal of tissue engineering and regenerative medicine

Hu T, Liu L, Lam RWM, Toh SY, Abbah SA, Wang M, Ramruttun AK, Bhakoo K, Cool S, Li J, Cho-Hong Goh J, Wong HK.
PMID: 34687157
J Tissue Eng Regen Med. 2022 Jan;16(1):63-75. doi: 10.1002/term.3260. Epub 2021 Nov 01.

High doses bone morphogenetic protein 2 (BMP-2) have resulted in a series of complications in spinal fusion. We previously established a polyelectrolyte complex (PEC) carrier system that reduces the therapeutic dose of BMP-2 in both rodent and porcine spinal...

A comparison of PET imaging agents for the assessment of therapy efficacy in a rodent model of glioma.

American journal of nuclear medicine and molecular imaging

Moonshi SS, Bejot R, Atcha Z, Vijayaragavan V, Bhakoo KK, Goggi JL.
PMID: 24116348
Am J Nucl Med Mol Imaging. 2013 Sep 19;3(5):397-407. eCollection 2013.

The aim of the current study was to assess the ability of PET imaging agents to detect early response to therapy in an orthotopic experimental rodent model of glioma. Clinically, MRI and [(18)F]FDG PET are routinely used but their...

Tuning sub-10 nm single-phase NaMnF3 nanocrystals as ultrasensitive hosts for pure intense fluorescence and excellent T1 magnetic resonance imaging.

Chemical communications (Cambridge, England)

Zhang Y, Lin JD, Vijayaragavan V, Bhakoo KK, Tan TT.
PMID: 22936349
Chem Commun (Camb). 2012 Oct 25;48(83):10322-4. doi: 10.1039/c2cc34858f.

We report ultrasensitive sub-10 nm NaMnF(3) nanocrystals codoped with Yb(3+), Er(3+)/Tm(3+) ions, and their intense pure red and near-infrared upconversion emissions in the presence of Mn(2+). The nanocrystals showed excellent T(1) contrast in 7 T MRI, implying their potential...
