The ‘Essence’ of our Enterprise
23 October 2015 2
Vision: To be a premier global biotech that employs human translational platforms for the discovery & development of novel diagnostics, biomarkers & drugs with better clinical outcomes
Mission:• Build a systematic archive of ethically consented,
anonymized human samples & associated data for developing novel biomarkers & diagnostics
• Leverage primary human tissues & stem cells for disease modeling, target & drug discovery with higher rates of clinical success
• Use of tissues for R&D, NOT for regenerative purpose
Saarum Sciences & Sapien Biosciences were initially set-up as two separate entities. We are in the process of merging both operations into Sapien Biosciences for better synergy

We have successfully cultured
high grade gliomas (SB.144
shown here) and U87MG cells in
serum free media on non-treated
plates for 10 to 15 days to form 3
Dimensional spheres known as
neurospheres. Such neurospheres
better represent human tumor
biology in vitro and can be used
for drug screening.
CSC evaluation is underway

Observation: Anaplastic astrocytoma (SB.6129) cells were cultured in non-treated 6 cm dishes in serum-
free medium as spheroid cultures (neurospheres) for 7 days. Then, neurospheres from Passage 2 were
stained with Calcein-AM and Propidium Iodide to detect the live (Green, Calcein-AM) and dead (Red, PI)
cells within neurospheres. Image shows that more than 95% of cells in neurospheres were alive.
H & E staining of SB.6129 neurospheres as Paraffin embedded spheroids
Observation: Anaplastic astrocytoma cells (SB.6129) were cultured in non-treated 6 cm dishes in serum-
free medium as spheroid cultures (neurospheres) for 7 days. Then, egg albumin cell blocks were made
with these neurospheres, followed by formalin fixation and processing for paraffin block preparation.
Image above is an H&E stained section from the block showing a group of tumor cells with well preserved
nuclei and cytoplasm. Dead cells stain black. Only 4-5 cells appear to be dead in the entire neurosphere
confirming >95% cells being viable, as also shown by calcein staining in the previous slide.

Observation: U87MG and one high grade glioma cell culture was
treated with Bendamustine at the concentrations indicated above. Dose
response curves were used to calculate IC50 values; the calculated IC50
value for both cell types was ~300 uM.
Dose-response of Compound B in Anaplastic Astrocytoma Neurospheres
• Compound B concentrations tested were 468 nM, 938 nM, 1.8 uM, 3.75 uM, 7.5 uM, 15 uM & 30 uM.
• Drug treatment was performed for 3 days (72 h) in triplicate.
• After incubation, WST-1 was added to samples and incubated for 3 h.
• The absorbance was read at 420 nm & 630 nm.
Observation: Treatment of primary anaplastic astrocytoma neurospheres with Compound
B demonstrated significant inhibition of viability, with IC50 between 0.9-1.9uM.

Migration Assay1. Anaplastic astrocytoma (SB.6129) cells were plated in 6-well plate for wound healing assay (migration assay).
2. Cells were grown to confluency in 6-well plate in their regular growth medium. Cell cultures were scratched with a 200 µl sterile pipette tip and washed with PBS to remove detached cells.
3. Cells were treated with 300 µM Bendamustine(duplicate) in parallel with 0.25% DMSO as control.
4. Images were acquired at 0h, 24h & 48h time points.
5. For automated image analysis, the acquired image data set was analyzed with the TScratch software.
