Indaba ngamaseli ethu: Ake sifunde ngokuhlolwa kwe-Flow Cytometry ngendlela elula!

Wake wezwa ngokuhlolwa okubizwa ngokuthi i-Flow Cytometry? Mhlawumbe udokotela wakho ukutshelile ngalolu vivinyo. Noma mhlawumbe lusha kuwe. Kodwa-ke, luwukuhlolwa okubaluleke kakhulu okusisiza sithole ulwazi oluningi mayelana namaseli emzimbeni wethu. Namuhla, sizokhuluma ngakho ngendlela elula ongayiqonda.

Kuyini i-Flow Cytometry?

Kalula nje, i-flow cytometry iwukuhlolwa kwelebhu okusetshenziselwa ukuthola imininingwane ngamaseli noma izinhlayiya ezincane emizimbeni yethu. Cabanga ngakho njengomseshi omncane ohlola ngaphakathi kwamaseli ethu.

Ukuze wenze lokhu, okokuqala isampula yamaseli akho (okungaba yigazi, umongo wamathambo, noma ezinye izicubu) iyancibilika oketshezini. Ngemuva kwalokho, uchwepheshe welebhu unezela amadayi akhethekile e-fluorescent antibody kumaseli. Lawa madayi ayaqaphela futhi anamathele kumaphrotheni athile ngaphakathi noma ngaphakathi kwamaseli. Ngamanye amazwi, anamathisela ilebula elincane, noma 'ithegi,' kulawo maphrotheni. Le nqubo ngezinye izikhathi ibizwa ngokuthi i-Fluorescence-Activated Cell Sorting (FACS) .

Lawa maseli alungisiwe abe esefakwa emshinini obizwa ngokuthi i-flow cytometer. Into emangalisayo ukuthi, ikhompyutha exhunywe kulo mshini ingahlaziya amaseli angaba ngu-10,000 ngomzuzu owodwa nje! Akusheshi lokho?

Ngakho-ke, lokhu kuhlolwa kusetshenziselwani?

Odokotela basebenzisa lolu vivinyo lwe-flow cytometry ezintweni eziningi. Ngokuyinhloko:

• Ukubalwa kwamaseli: Thola ukuthi mangaki amaseli akhona kusampula.
• Ukuhlela amaseli: Hlukanisa futhi ukhombe izinhlobo ezahlukene zamaseli.
• Ukunquma izici zeseli kanye nomsebenzi: Thola izinto ezifana nesimo seseli nokuthi lisebenza kanjani.
• Ukuxilongwa nokwelashwa komdlavuza wegazi nomnkantsha: Lokhu kubaluleke kakhulu ekutholeni izifo ezifana ne-leukemia kanye ne-lymphoma.
• Ukuthola ama-biomarker: Lezi yizilinganiso ezingabikezela ukuthi umdlavuza uzoziphatha kanjani nokuthi uzosabela kanjani ekwelashweni.
• Ukuhlola Ama-Immunophenotyping: Thola futhi uhlukanise izinhlobo ezahlukene zamaseli omzimba emzimbeni wethu.

Ukuhlolwa kwe-flow cytometry kwenziwa nini?

Odokotela basebenzisa lolu vivinyo ukuthola ulwazi olujulile mayelana namaseli angaphakathi emizimbeni yethu. Ngokukhethekile:

• Funda ngamaseli esimiso somzimba sokuzivikela: Bona ukuthi mangaki amaseli alwa nezifo esinawo emizimbeni yethu nokuthi ayizinhlobo zini.
• Thola amangqamuzana omdlavuza futhi uqonde uhlobo lwawo: Thola ukuthi amangqamuzana omdlavuza ahluke kanjani kwamanye amangqamuzana nokuthi yiziphi izici zawo.
• Cwaninga ngezimo zezokwelapha eziyinkimbinkimbi:
• Umdlavuza wegazi: Isibonelo, izifo ezifana ne-leukemia kanye ne-lymphoma.
• Ezinye izinkinga zegazi: Isibonelo, izimo ezifana ne-paroxysmal nocturnal hemoglobinuria (PNH) kanye nokuntuleka kwe-antithrombin.
• Ukusebenza kwesimiso somzimba sokuzivikela: Hlola izifo ezifana ne-AIDS (HIV) kanye nokuntuleka kwesimiso somzimba sokuzivikela okuzuzwe njengefa.

Enye into ukuthi, ngezinye izikhathi ngemva kokubala kwakho igazi okuphelele (i-CBC) sekuqediwe, uma kudingeka ulwazi olwengeziwe ngokusekelwe emiphumeleni, lokhu kuhlolwa kwe-flow cytometry kungenziwa. Ngokukhethekile, uma i-CBC ikhombisa ukwanda kohlobo lweseli olubizwa ngokuthi ama-lymphocytes, uma kukhona ukungalingani kwezinye izibalo zamaseli, noma uma ikhombisa ukuba khona kwamaseli egazi angakavuthwa, lokhu kuhlolwa kungayalwa.

Lokhu kuhlolwa kubaluleke kakhulu hhayi nje ekuxilongeni umdlavuza, kodwa futhi nasekuphatheni umdlavuza. Okungukuthi:

• Qagela ukuthi ulaka lomdlavuza lunjani.
• Thola ukuthi umdlavuza uzosabela yini ekwelashweni okuthile .
• Lokhu kusiza futhi ekunqumeni ukuthi umdlavuza uphinde wabuya yini ngemva kokwelashwa.

Lo mshini we-flow cytometry usebenza kanjani? Kuyamangalisa!

Lo mshini we-flow cytometry uhlaziya izakhiwo zomzimba nezamakhemikhali zamaseli ngokushesha okukhulu. Cabanga ngakho njengokubuka amaseli ngekhamera esheshayo kakhulu. Nansi indlela osebenza ngayo:

1. Ukulungiselela isampula: Okokuqala, uchwepheshe welebhu uthatha isampula yegazi lakho, izicubu, noma umongo wamathambo bese ewuncibilikisa oketshezini (olubizwa ngokuthi 'ukumiswa '). Bese, njengoba kushiwo ngaphambili, kufakwa udayi okhethekile obizwa ngokuthi 'ama-antibodies ane-fluorescently tagged' emaselini. Isixazululo seseli esilungisiwe sibe sesifakwa ku-flow cytometer.

2. Ukulungiswa kwamaseli kanye nokukhanya kwelaser: Ngaphakathi komshini, la maseli ahlelwe ngomugqa owodwa, elinye lilandelana. Cabanga nje, njengezingane zesikole ezibekwe umugqa. Bese, lo mugqa wamaseli udlula phambi kokukhanya kwelaser, ngalinye ngalinye. Lapho ukukhanya kwelaser kushaya amaseli, ukukhanya kuyahlakazeka, okungukuthi, ukukhanya okuhlakazekile.

3. Ukubala nokuhlunga amaseli: I-flow cytometer ibala amaseli futhi iwahlukanise ngendlela i-laser beam ehlakaza ngayo ukukhanya lapho ishaya amaseli. Uhlobo ngalunye lweseli luhlakaza ukukhanya ngendlela ehlukile. Umshini wenza lokhu ngokuthola lowo mehluko.

4.Idatha kukhompyutha: Lonke ulwazi (idatha) oluqoqwe umshini ngale ndlela luthunyelwa kukhompyutha exhunywe kuwo.

5. Ukwenziwa kwemibiko: Ikhompyutha ihlaziya le datha bese idala umbiko, ngokuvamile ngesimo segrafu yamachashazi noma yebha .

6. Ukuhlaziywa kwesazi sezifo: Ekugcineni, isazi sezifo – uchwepheshe wezokwelapha oxilonga izifo – uhlola la magrafu nedatha bese enezela idokhumenti equkethe okutholakele kwakhe kanye neziphetho embikweni wokuhlolwa.

Yini okufanele ngiyenze ngaphambi kokuhlolwa kwe-flow cytometry? Ingabe kukhona okufanele ngikusabe?

Ezimweni eziningi, ngaphandle kokuthi udokotela wakho ekunike imiyalelo ekhethekile, akukho ukulungiselela okukhethekile okudingekayo ngaphambi kwalolu vivinyo lwe-flow cytometry.

Udokotela wakho uzodinga isampula yegazi, izicubu, noma umnkantsha ukuze enze lokhu kuhlolwa. Lesi sampula ngokuvamile singathathwa ehhovisi likadokotela wakho ngesikhathi sokuvakasha kwakho. Ngemva kokuthathwa kwesampula, sithunyelwa elabhorethri ukuze sihlolwe.

Uma udokotela wezifo eseqedile ukuhlolwa kwe-flow cytometry, uzohlaziya idatha bese ethumela umbiko kudokotela wakho ocele ukuhlolwa.

Into ebaluleke kakhulu ukuthi azikho izingozi ezaziwayo njengamanje kuwe ngenxa yokwenza lolu vivinyo lwe-flow cytometry. Ngakho-ke ungesabi lokhu ngokungadingekile.

Injani imiphumela? Isitshelani?

Ngokuvamile kuthatha izinsuku ezimbalwa kuya esontweni ukuthola imiphumela yokuhlolwa kwe-flow cytometry, kuye ngelebhu udokotela wakho ayisebenzisayo.

Udokotela wezifo ubheka izimpawu ezisebusweni bamaseli akho, ezibizwa ngokuthi ama-antigen .

• Iseli eliphilile linephethini evamile ye-antigen efanele uhlobo lweseli kanye nesigaba salo sokukhula.
• Le ndlela ihlukile esitokisini esingajwayelekile . Lezi zinguquko zingabonisa ukuba khona kwe-leukemia, i-lymphoma, noma ezinye izimo zezokwelapha.

Uma udokotela wakho ethola umbiko wokuhlolwa, uzobukeza ngokucophelela inothi likadokotela wezifo, eliyisifinyezo sedatha ehlaziywe yikhompyutha evela ku-flow cytometer.

Lapho echaza imiphumela yakho ye-flow cytometry, udokotela wakho uzocabangela izimpawu zakho, umlando wakho wezempilo, kanye nokuhlolwa komzimba kwakamuva . Uzokuchazela imiphumela futhi akuchazele ukuthi isho ukuthini. Uzosebenzisa lolu lwazi ukunquma ukuthi yini okufanele ayenze ngokulandelayo.

Yiziphi izinhlobo zezifo ezingajwayelekile ezingase zibonise imiphumela engavamile?

Uma imiphumela ingavamile, kungabonisa izimo ezifana nalezi:

• I-leukemia ye-lymphoblastic enamandla
• I-leukemia ye-myeloid ebukhali
• I-leukemia ye-lymphocytic engapheli
• I-myeloma eminingi
• Ama-lymphoma angewona ama-Hodgkin (lawa angafaka kokubili izinhlobo ze-B-cell kanye ne-T-cell)

Uma imiphumela ingajwayelekile, kuzokwenzekani ngokulandelayo?

Udokotela wakho uzoxoxa nawe ngemiphumela yakho ye-flow cytometry kanye nezinketho zokwelapha ezingaba khona. Lo mbiko wokuhlolwa uzosiza udokotela wakho aqonde ukuthi isimo sakho sinolaka kangakanani, ukuthi ukwelashwa okuthile kulungile yini kuwe, nokuthi kungenzeka kangakanani ukuthi umdlavuza wakho ubuye ngemva kokwelashwa . Uzosebenzisa lonke lolu lwazi ukudala uhlelo lokwelashwa olukufanele.

Ezinye izifo zithatha isikhathi ukuzixilonga. Kungenzeka ukuthi uke wahlolwa kaningi, kodwa awukabi nayo impendulo efanele, futhi ungase uzibuze, "Kuthiwani uma ngenza olunye uhlolo?" Kodwa ngikholwe, lolu hlolo lwe-flow cytometry lunganika udokotela wakho ulwazi oluningi olubalulekile mayelana namaseli emzimbeni wakho. Ngeke nje lusize ekuxilongeni lesi sifo, kodwa luzokusiza futhi ukuthi wakhe uhlelo lokwelapha oluqondene nawe.

Ngakho-ke, yiziphi izinto okudingeka sizikhumbule kukho konke lokhu? (Umyalezo Wokuya Ekhaya)

Kulungile, ake ngifingqe amanye amaphuzu abaluleke kakhulu kulokho esikhulume ngakho:

• I-Flow cytometry iyisivivinyo esithuthuke kakhulu esihlola amaseli ngokujula.
• Lokhu kusiza ekuxilongeni umdlavuza wegazi, izinkinga zesimiso somzimba sokuzivikela, kanye nezinye izifo eziningi .
• Ukuhlolwa kuvame ukuhilela ukuthatha isampula yegazi, umongo wethambo, noma izicubu .
• Lokhu kuhlolwa akudingi ukulungiselela okuningi ngaphambi kokukwenza, futhi azikho izingozi.
• Imiphumela inikeza udokotela ulwazi olubalulekile ngesimo sakho, ukwelashwa okufanele, nokuthi lesi sifo sizoqhubeka kanjani .
• Leli ithuluzi eliwusizo kakhulu elisiza udokotela wakho ukuthi ahlele uhlelo lokwelashwa olufanele wena .

Ngakho-ke, uma udokotela encoma ukuhlolwa kwe-flow cytometry kuwe noma kothile omaziyo, ungesabi. Kubone njengendlela yokuqonda kangcono impilo yakho futhi kukusize uthole ukwelashwa okungcono kakhulu. Uma unemibuzo, buza udokotela wakho.
