Conditioned medium – of adipocyte derived stem cells

 Ideally, a stem cell for regenerative medicinal applications should meet the following criteria: Regenerative Medicine :Uses the body’s own stem cells and growth factors is an alternative therapeutic strategy for repair of damage tissue, and becoming predominant cell base therapy

Regenerative medicinal applications should meet the following criteria: Can be found in abundant quantities (millions to billions of cells) Can be harvested by a minimally invasive procedure Can be differentiated along multiple cell lineage pathways in a regulatable and reproducible manner. Can be safely and effectively transplanted to either an autologous or allogeneic host

 With the increased incidence of obesity in the Indonesia and abroad, subcutaneous adipose tissue is abundant and readily accessible. Approximately 400,000 liposuction surgeries are performed all over the world each year, These procedures yield anywhere from 100 mL to >3 L of lipoaspirate tissue

 ADSCs secrete various growth factors that repair and replace the defective surrounding cells Also a good raw material for skin regeneration, reepithelialization, wound healing and wrinkling care instead of ADSC itself

Oxygen levels & Oxygen sensing, HIF Genetic exogenous stability 1 responseoxidative stress Cytogenetic analysis, gene expression, bioenergetics studies Culture grown in -Increase genetic physiologycal 20% instability oxygen -Decrease glycolysis Culture grown in -transcriptional activation standard 3% in HIF 1A target genes oxygen - Inhibition oxygen consumption

RESULTGrowth of hMSC at 20% O2 reduces lifespan, increasesoxidative stress and the rate of telomere shortening Cell growth Telomerase shortening & cell senescence

Growth of hMSC at 20% O2 increases DSB generation andchromosomal instability. DSB level (53BP1 marker) DNA damage & chromosomal aberration

Exogenous source of ROS cause growth defects &genetic instability

DISCUSSION -Promotes DNA damage & Culture of senescencemammalian cells -Chromosomal aberration during at 20% oxygen long term culture Importance of biosafety Culture ADMSC at in cell 3% 0xygen therapy Increase growth rate -No evidence of spontaneous immortalization -- reduce telomere shortening rate decrease structural chromosomal aberration

Significant upregulation of gene Balanceexpression in cells grown at 3% oxygen bioenergetics tension related to HIF 1A stabilization pattern HIF 1A decreases OXPHOS system by downregulating mitochondrial ATP production & oxygen consumption Autocrine & paracrine effect in cell growth & senescence Implication of gene ontology analysis (HIF 1 dependent gene expression)
